Can you get a cavity even if you do not eat sweets?

You can get cavities without eating sweets.
Anything you eat, if it sits in the nooks and cranies of your teeth and mouth, can cause problems. Also, the acidic nature of some foods will also cause decay.

Lots of other things have sugar like fruit for instance . Cavities are not just down to sweets i don’t think . But he is the dentist so he would know what he is talking about

And according to scientists fluoride is bad for the teeth so that could cause them also .
Maybe

Yes, you can. Dental caries is caused by the combined effects of certain bacteria in your mouth plus sugar. However, many things have sugar in them, so, not having a sweet tooth doesn’t mean you aren’t ingesting some sugar.

Have you ever had your wisdom teeth removed?

all 4 have been removed.

I’m going 4/9 to get it checked out :(

Absolutely. Not only sweets cause cavities. Cheese is supposedly one of the worst offenders in tooth decay.

Yes, but it is amazing how a tooth can slow or almost stop advancing in decay. I still have had two cavities and they have stayed the same for years.
One dentist can say you have 3 fillings, then you can go to another; he or she will say you only have one.
Also, a lot has to do with your tooth enamel you were given. My wife is religious with her oral hygiene; I am much less so, yet I hardly ever get them and she always does and her diet is not much different.

@Garebo Right. It’s probably not an enamel issue, but rather that she has “bad bacteria” in her mouth, and you don’t.

Got me? That is what she thinks, and I have no better explanation.
What bad bacteria does she have, that I don’t?

@Garebo Probably a combination of bacteria that lead to dental caries.

We learn so much from our WIkipedia.

@Garebo I feel ashamed. I almost never cite wikipedia (since I don’t really trust it), but there weren’t any good medical websites like the CDC or eMedicine with useful information. Sorry.
