Tooth pain

Hey, molar I had an amalgam filling in cracked like, 6 months ago. I went to the dentist about 4 months ago and the guy told me that the crack was too tiny to fix. about 85% of the filling is still in place outside of a small spot at the corner of the top of my tooth.

So problem is that it's sensitive. I'm worried I may have decay under the surface of the filling but after constant inspection, no surface portions of the tooth are even remotely stained. Even the amalgam still has its silver color.

He told me that cracks like that often cause pain because of acid leaking into it.

Anyways, it hurts on occasion, and yes specifically when I am drinking acidic beverages but also at other times during the day. It's not sensitive to heat or cold or pressure.

But I also smoke so that caused a slight recesion of me gum line so I think that might be the source of the problem but unlikely.

And I also have tmj, so that could also be the source of the problem (probably the reason it cracked in the first place).

I guess I'm just worried here because I hate tooth decay and I need some reassurance that it's not.

A cracked restoration will most often lead to recurrent decay since it provides the nooks and crannies bacteria need to make home. Decay takes some time to progress (often 1-2 years to become visible to the eye). Radiographs are more accurate then just visually looking at the tooth to see if there is recurrent decay since you cannot see what is going on underneath the filling.

Keep a close watch on the tooth and maintain good oral hygiene. The filling must be deep and close to the pulp and that is why removing the entire filling will make the preparation even larger which may lead to root canal treatment to avoid overly traumatized and sensitive tooth.
WHen you say you have TMJ problems what exactly are your symptoms? Have you consulted with an oro-facial pain specialist?

He gave me an xray which didn't show anything, but I also heard that existing fillings can interfere with detection through that method. Radiograph I could request I suppose.

And I have been keeping watch/practicing good oral hygiene, at least to my knowledge. Anyways, I do have TMJ, was diagnosed by a doctor just recently. I think the filling fracture was likely from bruxism. Which sucks.

But I do have a night guard too so that helps. I hope that the filling is small enough to take another beating, i'd like to prolong destroying this tooth as long as I can. Because my other molars are following the same route (lots of fillings at a young age).

I'd almost prefer extracting them.

I see. Good oral hygiene would be two brush twice daily with flossing, ue fluoride mouthwash and cut back on frequent snacking. It is better to eat 3-4 times daily than snacking constantly. If your are willing to purchase a prescription then ask your dentist for prevident 500 plus and brush with it twice/day.
Trust me you do not want extractions and amalgam is more durable and would serve for a while if you keep good hygiene. Extraction will require implants and they are contraindicated if you smoke. Smoking is also associates with gum disease and periodontitis. If you ever consider quitting talk to your dentist.
It is good that you are using night-guards to help with bruxism. If your were also clenching at night then you would notice muscle pains and spasms. ANother trick is to put a little MI paste or ordinary baking soda inside the night-guard trays at night and wear them helps to make enamel stronger.
