today we are going to talk about what a cavityis. a cavity is basically a small dental infection of the tooth. it's usually comprised of bacteriaand it's a bacterial infection that kind of occurs in different surfaces of the tooth.when caught very early it's usually not a very, painful procedure however, as it getsmore advanced it can get closer and deeper down into the nerve and cause irritation suchas hot cold sensitivity, biting sensitivity and gum tenderness. the way we treat a cavityis with what we call a filling and in order to do that we basically have to go in andremove the cavity make sure that the cavity has been removed and there's no more bacterialinfection.then we proceed on with the filling. in this model basically what we have is adesignation of what a typical cavity would
look like. when you are going around the mouthlooking for cavities we are looking for basically dark heavy stains or anything that looks alittle unusual. so here on this tooth we basically have this dark like basically highlightingan example of what a cavity looks like. this is on the second tooth on the very back onthe upper right and what you are seeing is a very heavy stain with a little bit of cavity.once we've identified that that's a cavity at that point that's when we decide that weare going to do a filling. so the first step in basically doing a filling is going in andbasically numbing up or anesthetizing the patient. we do this in order to make the patientvery comfortable so that when we go and remove the cavity it does not cause any irritationor annoyance to the patient. we'll take what
we call our hand piece and basically go inthere and lightly clean out the cavity like so. and basically once we've cleaned out thecavity, what we'll do next is go in with our instruments and basically check to ensureall the stain is removed and there isn't anything sticky or anything a little irritating tothe tooth. once we've verified that all the cavity has been cleaned out, the next stepwould be to actually do the filling. so what we do is we take our tooth colored fillingmaterial and we gently add it to the space were we had taken the cavity out. so againit's a very, it's a tooth colored material that typically blends very nice and very clean.so then we go through and lightly put our material right into the tooth and once we'vehave it filled we use a special light to set
it up. filling material start out very softand in order to be able to mold them permanently to the tooth. once it's been molded then weuse a special light that when shined on the material it turns it very hard and makes itvery strong. we'll put our light over top of the tooth that we did the filling and byactivating the small button we actually initiate a light reaction that makes the material reallyhard. and that typically takes anywhere from twenty to thirty seconds depending on howbig the cavity was and how thick the filling would be. once that process has been completedthe dentist will go back and check the filling to make sure that it's set up and it's hard.so what started out as a very soft is now very hard with the curing light. once we'veverified that the tooth has been filled the
last step would be to go in and check thebite to ensure that the patient was not biting heavy or hard on this tooth. and that is prettymuch a filling.
