>>54719>there is no reason to suspect she has poor oral hygieneIt's a fair assumption. Missing adult teeth are usually attributed to decay as a result of poor oral hygine or some type of physical trauma. It takes quite a bit to knock a tooth out, but sure maybe she fell or something
>All other teeth are actually in a great condition and shapeUnless you have other examples, the only thing we have to go off of is the OP. It's blurry but she is certainly missing at least one tooth above, maybe another on the bottom. It's hard to make any further evaluations. I understand you want to give her the benefit of the doubt here, and maybe she just can't afford to get it fixed, but it's a stretch to claim leaving missing teeth unrepaired is proper oral hygine, gone unchecked they can cause even more issues.
