Wisdom teeth and sealants...is my dentist full of it? Much pointage for best answer!?

Okay, so I'm going to be 30 in 5 days. My wisdom teeth have been in the same position for over a decade; the tops two are all the way in and have never caused me trouble. The bottom ones are coming through; they, as well, are asymptomatic. Instead of having them ripped out of my face, I inquired about having dental sealants painted on them to protect them. My dentists said that'd do no good but didn't say WHY.

I did my own research. On the Ontario Dental Association's site it says sealants are actually very effective for protecting wisdom teeth. I have insurance, and I'm not afraid of the procedure...but why do it if there's a viable reason not to? Sealants are cheap, effective, and can last for years (though they have to be monitored and redone if they begin to wear).

Obviously my dentist is hip to the fact that there's quite a large wad of cash to be made by removing wisdom teeth instead of simply sealing them. I think he's trying to d!ck me around. What's your opinion?

It depends on whether plaque can be prevented from creating cavities or infection. Now, fissure sealants are fine for preventing decay starting in the top surfaces of FULLY EXPOSED teeth of any type, including wisdoms, but you say your bottom 2 are still coming in.
At the age of 30, if they're not in place and fully clear of the gum, then they'll never make it.
1. If your wizzies are coming straight up but are still partially covered by gum, then you run the risk of gum infections or decay in the top surfaces. You could get fissure sealants in there with difficulty, but that won't prevent gum infections (pericoronitis).
2. If they are coming up at an angle, then the tip of the wizzies may be resting BELOW the gum surface against the root surface of the molar IN FRONT. This is a bad situation because plaque will accumulate there where you can't clean it, and you run the risk of developing decay in the front maolar at great depth. Almost impossible to repair.
3. There is no guarantee that your wisdom teeth will ever give you trouble, but if they do, you'll regret not having had them removed for the above reasons. As dentists we see lots of problems caused by retained wisdom teeth, and if they're only partially exposed thru the gum, then I strongly advise extraction. And we're not in it for the money - taking out patients' wizzies is not a glorious task that endears us to patients. I send most patients off to an oral surgeon for day surgery, so I'm not getting any money there.
Recent example - patient arrives with impacted wizzy against molar in front (2nd molar). 64 years old. Had 1st molar extracted many years ago. 2nd molar has deep decay on root surface. I quote extraction of wizzy, RCT for 2nd molar, crown for 2nd molar = $2000+. Instead, patient elects to extract 2nd molar and keep useless tilted wizzy because of cost. Will now have no useful chewing ability on this side of mouth. Why didn't someone convince him to have the wizzy out when he was much younger and before any damage was done?
Get them removed or get a 2nd, 3rd opinion.

My understanding is that wisdom teeth can push other teeth around and cause bigger dental problems. That could be why.

If I were you, I would just go for the sealants and then if they don't work out go with the surgery. (But that's just me - and I don't have wisdom teeth - I am the next step in evolution - I was born without them altogether!)

removing teeth isn't that much money. Unless they are impacted and they have to cut them out, then the price will go up. As you get older, your teeth shift in your mouth. He probably wants to prevent damage of your other teeth. IF you are really in doubt, get a second opinion.
