Question
I have never had any cavities, but I have one molar that my dentist said just never completely sealed itself. It's only on the lingual side of my mouth and it doesn't bother me (had it over 10 years). But he's pressuring me to have it filled to 1. prevent a cavity and 2. prevent fracture. I'm a med student and feel knowledgeable enough to understand these risks if I don't go through with it. However, I've never had any work done to my teeth and don't feel this is completely necessary, especially when fillings can lead to sensitization and discoloration. What do you think? Could I put this procedure off until, say, I get a cavity?

I think I know what he is saying. Now remember that I am just guessing here. I cannot give you any definitive answers without seeing things in person. It sounds like what we call a non-coalesced groove. Feels open but not decayed yet. Usually it will decay but who knows when. May not happen for years. I do not think it will fracture. Here is what I would recommend: pit and fissure sealant. This is not a filling. It is a thin resin that we flow over deep grooves to try to prevent future decay. Simple and pain free and way less expensive than a filling. See if he likes this idea. If not you always have the option of getting a second opinion. Good luck,
