Small indentation on a molar filling I got a year ago - should I be concerned?

[aran215]

Hi everyone,

About a year ago, my bottom left second molar broke in half and was rebuilt with a large white composite filling (no crown or root canal).

I've recently noticed what looks like a small indentation on the chewing surface (see attached photos below). Could this be wear, decay, or a failing filling ?

Any advice or opinions would be greatly appreciated. Thanks!

Doesn't look like decay. Could be an area of wear due to grinding. If it is not sensitive, then I would not worry as yet. But you should make sure that you are not a bruxer.

Thanks for your reply, Dr M. That is reassuring to hear. I haven't noticed any sensitivity or pain from the tooth, so I will keep monitoring it.

I wasn't aware I might be grinding/clenching my teeth. Are there any signs I should look out for that would indicate I am a bruxer?

Some people experience a headache or muscle pain in the cheeks in the mornings when they wake up. There could be pain on more than one tooth, or sensitivity. Sometimes there are no symptoms, but the signs are there on your teeth. As your dentist to have a look the next time you go for a check-up.

another huge sign to look out for is a scalloped tongue where you see ridges on the sides or a white line running along the inside of your cheeks from clenching tight.. you might also notice your jaw muscles feel super tired or stiff while eating breakfast.. since it was a really large composite filling on a back molar those do wear down faster than natural teeth anyway under heavy pressure.. a custom nightguard from your dentist is honestly a lifesaver to protect it from wearing down or chipping further

That tooth takes a lot of pressure when eating and will often crack mesio-distally resulting in an extraction. I would have it crowned, preferably high-precious gold alloy, or zirconia.
