Re: Question about dentists
There r 2 ways to detect cavities. One is X-ray, the other is by using the hook instrument and sticking it into the 'sensitive' area to check for "mushiness". If the hook gets stuck in the area, its a cavity or on its way to becoming a cavity. These mushy areas may or may not appear on a X-ray depending on its size. X-ray will typically point out the obvious cavities. Also, if both doctors aren't x-raying the same exact area? They will get different results. Even if u feel like both dentist are x-raying the same exact area on your right cheek (for example), depending on where they place the bite guard in ur mouth, they may be x-raying your top teeth (right cheek) or bottom teeth (right cheek). Best way to get peace of mind would be to request copies of ur X-ray (usually for a fee) for the one with the cavity and show it to ur doc that hasn't found any cavity (or vice versa). It may be that they're both x-raying different areas which is why one is finding the cavities owhile the other one isn't.
For certain teeth, depending on location, an X-ray just serves as confirmation (for insurance companies) that the cavity exists. A seasoned dentist can look at a tooth that looks like it may have a cavity because of slight discoloration, and diagnose just with the hook instrument without needing an X-ray. If the hook sticks in to the tooth, hands down, it's a cavity. But procedure requires an X-ray to check the depth and how to proceed- filling or root canal.
As far as the wisdom tooth, I have no comments. I don't understand any work done to wisdom teeth!!!!!!
Oh, and I'm not a dental professional. My mom is a dental assistant and I've spent a lot of time hanging out at the office :-).
