Do Dental Crowns Ever Come Off?

A local Cuffley patient asks for advice….

Another in our occasional series of questions received at The Lodge Dental Suite which we feel might be of general help to some of our patients.

Q. Hi .. I moved to Cuffley a little while ago and haven’t yet got around to registering with a dental practice. My teeth are generally OK but one tooth has been filled a few times now but the fillings never seem to last long. My previous dentist suggested that if it didn’t stay in place this time, then he would have to consider a crown. I mentioned this to a friend who rolled her eyes and said that her crown had been nothing but trouble and kept coming off. I don’t want to keep having the tooth filled, but if a crown keeps coming off, is that really a better option? Any suggestions please?

Hello, and thank you for your email. As with all cases which we are told about via email or phone conversation, the only way to be sure of the problem and correctly diagnose it is to have your teeth examined by one of our  Cheshunt dentists. We are very conveniently situated for Cuffley and already have a number of patients who come to see us from there. With regards to your problem, it is possible that the cavity is bordering on being too large for a filling. Most fillings should last for a number of years and the fact that yours keeps coming out indicates that perhaps a dental crown would be a better choice. We will assess this when we meet you.

To place a crown, the tooth is shaped in a way that ensures that the crown can be attached with a strong dental adhesive in a way that holds it securely in place. There is no real reason why a crown should become detached as easily as your friend indicates hers has. Naturally, the adhesive will gradually lose some strength over time, but this typically only happens over several years. A blow to the tooth can weaken the bond and other factors such as teeth grinding may also come into play for some patients.

The other main reason for a crown to become detached is if the underlying tooth starts to decay. This can obviously weaken the bond between the crown and the natural tooth and is yet one more reason to look after your teeth. In some instances a ‘post’ may be used when attaching a crown. This is typically (but not always) after root canal treatment where a post is inserted into the tooth canals before the crown is attached. This gives the tooth additional strength and stability.

Generally, dental crowns should stay attached and should be perfectly adequate for your everyday needs; only infrequently do we see patients who need to have a crown re-attached. One word of caution though; if you do have a crown and it does become detached, it is important to have it reattached by a dentist and you should not attempt to do this yourself!

I would recommend a call to our friendly Cheshunt dental team on 01992 643388 to arrange a consultation where we can examine the problem and discuss the options with you. We look forward to seeing new patients from the Cuffley area here at The Lodge Dental Suite.
