This will often be due to an inadequate underlying tooth shape and decay. Other reasons include your bite hasn’t been measured up properly in line with your other teeth, moisture contamination when the crown was being fitted and  poor impression technique when the crown was being measured up.

If your crown hurts 6 months after it was placed, there is something wrong such as decay underneath the crown, a marginal gap under the crown or that the nerve is being irritated and now is infected. A crown may initially have been fine and only starts to hurt 6 months later. This can be due to decay or that the nerve has become infected.

Random sensitivity with a tooth crown usually means that the pulp or the nerve of the tooth is becoming infected. You should not ignore this as a dental abscess may result and then eventually you may have to lose the tooth.

The main two reasons are that you have a cavity and also due to lack of proper contact point. The cavity will be in the space between the crown margin and the underlying tooth itself. The contact point refers to the fact that teeth touch each other and if the crown is not touching the adjacent tooth tightly enough, then that creates a space for food to get down. In these cases the crown needs to be taken off and if there is decay, then that needs to be cleared out first before a new crown can be made. If there is a lack of contact point then a new impression needs to be taken and the technician will make a new crown that has a good contact point which prevents any food getting in underneath and causing you problems.

Sensitivity which is not going away after a crown has been put in needs to be checked for several things. This includes whether decay is occurring underneath your crown. It can also be that you have a gap between the margin of the crown and where your natural tooth join is. With some cases, it can also mean that the pulp or the nerve inside the root is being continuously irritated and a root canal treatment is required. It is usually best to have the tooth x-rayed and examined by a dentist.

A black line around is a Zirconia crown usually does not happen but if it occurs it usually indicates contamination with moisture and blood when the crown was being put on. In these cases it is usually necessary to replace the crown if it is affecting your smile especially around your front teeth. A black line may also indicate the appearance or discoloration of the root underneath your tooth if it has been root filled or perhaps there may even be an infection inside the root. Decay around the edge of a Zirconia crown will appear as a black line in its early stages.

Sensitivity under a new crown can be normal at first but tends to subside quite quickly. If you have an old crown and it suddenly becomes sensitive than that usually indicates a problem such as with the underlying nerve. It may also be that you have a gap that has appeared under your crown and bacteria are therefore getting in. Finally decay can still occur under a crown and that can also start to irritate the nerve causing sensitivity.

A black line can mean that the join between the edge of your crown and where it meets your underlying tooth around the gum line has become stained. It also can mean decay is occurring or the crown is leaking. Some crowns made of porcelain have metal underneath to increase their strength but the metal can show up as this black line.

The black line around your dental crown indicates the border of the crown with the junction of your underlying natural tooth.  The most common cause of the black line is due to the type of crown that you have. This type of crown most often will be porcelain fused to metal crown. The black line shows because of the colour of the metal underlying the porcelain at the gum line. Metal is used under a porcelain crown for strength but the aesthetics are not as good as an all ceramic porcelain crown.

This indicates a problem with the way the crown was made and also perhaps the way the crown was cemented in. If you keep on having your permanent crown put back on then you should ask your dentist why this keeps happening. Also make sure that your underlying tooth has no decay and has not broken off.

Continuous pain after a new crown is not normal. Initially after a new crown, your tooth may be a bit sensitive but this usually settles down within 24 to 48 hours. If you are getting pain under the new crown and is not going away or is getting worse, then go back and see your dentist as they may need to x-ray the tooth. It could also be that the bite is incorrect in which case your crown needs to be adjusted.

A crown may be a different colour depending on the material the crown is made from and the shade that was used to initially choose and match up your crown. Some natural teeth can be easy to match up to a crown and others can be extremely difficult. Front teeth are usually even more imperative to make sure that they match up as compared to back teeth which show less.

If your new permanent crown hurts then it could indicate decay or infection. It can also indicate a gap between the tooth and the crown underneath. In most cases if the pain continues it will be necessary to have a new crown made. If there is infection then you need to have a root canal treatment done in addition.

Initially ask your dentist to look and take an x-ray.  Usually it will be necessary to re prepare for the crown and tooth again from the beginning. This usually solves any problems and you get a new crown which will last a lot longer this time.

Pain under a crown usually indicates a problem with the nerve and possibly a

 root infection. If the pain is severe and prolonged then this needs to be x-rayed and the cause of the infection removed. It could be that the crown has a gap underneath and that’s why you are getting pain and once again the crown needs to come off and a new one made to close up gaps.

Decay under a crown usually appears brown or black depending how long it has been there for. Also there may actually be a cavity so you may be able to get your thumbnail or a tooth pick into the decay. In all cases it is necessary to have an x-ray taken and find out how extensive the decay is.

Tooth crown pain can be for a number of reasons including decay, a gap between the crown and underlying tooth or an infection in the root.

When a crowned tooth breaks off at the gum line it usually it’s necessary to make a new crown. This will additionally require a post placed inside the root for extra retention so that it doesn’t come off again.

A post actually reinforces the root so that this is less likely tohappen again in the future.

Once your crown has been put on permanently then the only way to change the colour is to replace the crown. The crown to be replaced has to be drilled off first. A new crown can then be matched up with your ideal colour in relation to your remaining teeth.

If your dental crown doesn’t match your teeth then it can be changed by making a new crown instead. The new crown can be constructed so that the shape and colour now matches with your other teeth.

Ideally the very moment your crown comes off you should have it put back on. Realistically it would be 24 to 48 hours. Any longer and you are increasing the chances that your crown won’t go back on properly again due to tooth and gum movement.

This is usually due to the tooth underneath which has to be retentive by the manner your dentist has shaped the tooth. The underlying tooth must be clean and be free of any decay. Finally, the process of putting the permanent cement is really important. The tooth and crown must be dry before the crown is permanently glued in.

Firstly clean and dry both the inside of the crown and your tooth. Then put your crown back on the correct way and see if you can bite on it comfortably. If the bite is comfortable then again clean and dry both the tooth and the crown. Finally put inside temporary dental adhesive. So, get some temporary dental glue from a chemist. Remove excess dental cement from the gum line with a tooth pick and in between the adjacent teeth by flossing.

A new crown can be sensitive in the first few days. After a week, things should settle down almost as to what they were before. If you are still getting pain after a week then your dentist should re-examine the crown and even take an x-ray to make sure there is no infection or gaps.

A gap in the crown can be repaired with a material that dentists use called glass ionomer cement. This depends on how big the gap is and where the gap is in relation to the crown and the underlying tooth.

Initially you can try putting a sensitive type of toothpaste around the edges of the crown however if the sensitivity is severe then that won’t get rid of it. You probably need to see a dentist and have an x-ray done. Severe sensitivity is usually that the nerve is being irritated. This can be due to decay or it can be due to the fact that there is a gap underneath a crown.

After a new crown, sensitivity can occur within the first 24 to 48 hours. After that it should settle down gradually and after a week you should be back to normal. Some patients can even take a few weeks for a crown to settle down. But if after two weeks the crown is still sensitive then go back to your dentist to have it rechecked.

A broken tooth at the gum line is usually fixed by placing a post with a new crown. The post goes inside the existing root and the exposed part is then used to hold a new crown hence the name, a post core crown.

Many teeth which have had a crown put on seem to settle down very quickly and certainly within the first 48 hours. Some teeth can take a little bit longer and they may take up to two weeks to settle down. If after two weeks the tooth is sensitive, painful or hurts when you bite on it, then it is a time to go back to the dentist and have an x-ray to see what the problem is.

Firstly you should brush the area as thoroughly as possible. Then you should try putting floss through. Pull the floss down firmly between the crown and the adjacent tooth right up to and under the gum line. Failing that, get an interdental brush and see if you can poke the food through to the other side. Finally if all else fails, use a toothpick gently to remove the food stuck under the crown.

With an experienced dentist you can have this done in one visit. During the visit the dentist will drill through the old crown and clean out the roots. Once there is no infection the roots will be sealed up and a filling placed through the access cavity which was made through the crown.

Sometimes it may be necessary to make a new crown afterwards once the success of the root treatment is finalised. The final result is checked by taking an x-ray afterwards.

If a crown has become discoloured, a new crown is usually necessary. This is done by taking off the old crown and taking some new dental impressions for a new crown using a different shade which matches as you want to be.

You can clue glue your crown back on with the temporary dental glue from the chemist. Don’t use super glue because that will cause you problems later on. Then go and see your dentist to have it put back on permanently again.

A new crown can cause slight pain and the most common reason is that it is initially trying to settle down. However after a week if the pain is not subsiding then you should go back to your dentist. Pain from a new crown can also be due to the nerve underneath your own tooth becoming infected.

Sometimes a cavity under a crown can be fixed usually using material called glass ionomer cement. It depends on the size of the cavity and where on the crown tooth surface you want to cover. In many cases a cavity under a crown cannot be fixed as easily and usually a new crown is required depending on the extent of the cavity.

It is fairly common that a root canal treatment has to be sometimes done through an existing crown. On any back tooth, you will usually use the biting surface of the tooth to get access to the root. On the front teeth you usually use the inside surface of the tooth so that the appearance is not affected. Almost a third of all teeth which have crowns will eventually need a root not treatment afterwards as shown through clinical papers on dentistry.

The colour of a crown can only be changed when the dentist is trying the crown in and showing it to you before having it on cemented permanently. Once the crown is on permanently, then the only way to change the colour is to take the crown off and make a new crown from the beginning again by taking new impressions or moulds.

A dental crown once put on permanently cannot be recoloured whilst still in your mouth. Therefore the only way to recolour, is to drill the crown off totally and ask the technician to make a new crown with the right colour match.

The answer is yes, but depending on the condition of the remaining root. If the root has extensive decay then that needs to be removed first. Sometimes a root canal treatment will be necessary if it hasn’t had one done already. Definitively a new post for retention then needs to put before in the root followed by a new crown.

Yes, this happens quite frequently. Usually if the tooth has not already had a root canal treatment, it will need a new root canal treatment. These crowns are called post-crowns and although they don’t last as long as some types of conventional crown, they can still serve many useful years for the patient.

Yes definitely you can. There are various procedures that will probably use be used including a root canal treatment, a post and core, and sometimes even gum surgery also known as crown lengthening. In all cases the dentist will take an x-ray before the work on the tooth which has broken actually starts.

A new crown should not have a gap underneath it. A gap usually indicates making for a new crown again. For a gap under an old crown it can also mean that there is decay occurring. The gap under a crown can become bigger as the decay gets worse.

A tooth with a crown can be sensitive like a normal tooth. Sensitivity from a crown tooth can be due to decay or possible infection in the root. Gum recession around a crown can also cause sensitivity to hot, cold and sweet things. It tends to last momentarily for only a second or two. Sensitivity that lasts longer can mean that there is decay under the crown or that the cement under the crown has washed away causing a gap to occur.

Gums generally do not grow back around crowns and if anything, they recede more as time goes on. If you are worried that the gum does not meet the crown then it may be necessary to replace the crown. This is only necessary if it is an aesthetic concern for you or there is an actual gap.

Food should not get under a dental crown unless the fit of the crown is not good enough. The gap could be around the gum line where the tooth meets the crown or it can be in between the crown and the adjacent tooth what we call in dental terms, the interdental space.

If it has been months after your tooth crown has been placed then you should be getting no sensitivity whatsoever. Any crown sensitivity is usually due to a gap under the crown or that the nerve under the tooth is becoming infected. Both of these can be verified by going to the dentist and having the crown checked and also having an x-ray done. Tooth sensitivity months after a crown has been placed usually can only be remedied by having a new crown. Depending on the cause of your sensitive crown, sometimes an additional root canal treatment is required.

Here are some red flags and advice when you are having cosmetic crown dental treatment problems.

1. If you feel pressurized into having your treatment carried out as soon as possible? How did they react to you if you said that you would like some time to consider?
2. For expensive and extensive cosmetic dental treatment gone wrong, always get a second opinion. Once you have got your second opinion, are the two treatment plans fairly similar or do they vary considerably and that could be a red flag sign.
3. Did the practice promote to you a free initial checkup? This can be a problem because a free dental check-up is obviously not free because they have to claw back that amount of time and cost from your treatment known as upselling.
4. When you looked at their website, was it quite sales orientated or not?
5. When you had been to the practice at least once, what was your overall gut feeling?  If you also went with somebody else for example your spouse, what was their opinion?
6. Is the practice happy to answer all your questions or do you almost feel that you are a nuisance for asking these questions?
7. Are you given several different options with regards to your cosmetic treatment or do you get the push into just one kind of treatment?
8. You should always ask that when something goes wrong with the treatment or extra work needs doing, who pays for this?
9. Finally, what are the rest of the team members like? Do they feel stressed out or are they friendly and relaxed?
10. Ask for a copy of the Practice Complaints procedure from the manager.
