Dentistry/Filling Keeps Falling Out


I have a filling at the outer side and rear side of tooth #28. I have no adult tooth #29 so there is a space there. The filling on #28 is at the base line or gum line. It was originally put in 9/2011. Then it fell out and was replaced on 4/2012. It has now fallen out again - 2/2013. The dentist has told me it is because all teeth wear down at the gumline and that this one due to no tooth next to it and tooth #5 impacting upon it with every bite, that the filling will not stay in place. Is that true? He also suggested getting a dental implant on that tooth to resolve the problem. That sounds a bit drastic for a tooth that is otherwise in good shape and doesn't cause me any problems. I wonder if it is the dentist's skill level, or material that he is using. I look forward to your comments.

Hi Chris,

I am sorry to hear about this.

If the tooth on top is hyper-erputed, this can cause the filling to get excessive force on it and may contribute to it falling out. I don't know if that is 100% the cause of the problem, but it can be a part of the problem.

Has your dentist ever tried adjusting the opposing tooth so it's exerting less force on the restored tooth?

In regards to the implant, if you are missing a tooth, then you do want to replace it. Otherwise, (as you know), the other teeth shift and become unstable. Nowadays, a dental implant is generally the best option. So yes, recommending a dental implant is not a bad idea.

I hope this helps somewhat!
