Many people think when we are getting older, our teeth will become loose and they will fall off eventually. This is WRONG. If you take good care of your teeth, they will function perfectly until your last day. I have seen 80 some year old lady with full mouth firm teeth and the only time she comes to see the dentist is for the regular dental checkup and cleaning.

When we consider about dental care, it includes both self-care and professional care. If you follow all the right instructions, there is a much smaller chance of having dental problems. But that doesn't mean you don't need to see your dentist. Regular checkup is really neccesary since it's relatively easy to fix when it's a small problem. For example, dental exam and x-ray can detect small/shallow cavities. But by the time you develop some sensitivity, it's a big/deep cavity now and it might be too late to just fill it. Then you need root canal and crown.

Talking about the gum disease, Dudu has said what I want to say. If you have concerns about the deep cleaning, talk to your dentist and the good communication is beneficial for both sides.
