Here it is first the dentist or the assistant may take your blood pressure prior to numbing you up. Next they may apply a topical anesthetic on your tissue. So you won’t feel the pinch from the needle then you may receive local anesthetic.
This way you’ll be super numb and you won’t feel any of the drilling or the filling. After they numb you up they will usually rinse out your mouth with water and wait for you to start getting numb. Once you’re numb the next step is to use a drill or an air abrasion instrument or a laser to remove the decayed area.
In this case in this blog the dentist is using a drill to remove the decay out of the tooth starting with the high speed handpiece drill. This specific high speed handpiece drill sprays out water. So there will also be a suction and or a saliva ejector in the patient’s mouth during the drilling to suction off the water.
Now the dentist is actually using the slow speed handpiece which is sometimes called mr bumpy to remove more decay. This drill does not spray out water but they usually keep the suction in there anyway. Because debris and different particles they don’t want anything flying around. Next the dentist may use a cavity detector and if needed the dentist will go back in with the hand pieces to remove the remaining spots of decay. By the way this blog is showing a small cavity on one surface of the tooth. Which is an extremely straightforward type of cavity to fill.
So sometimes cavities will contain more surfaces. That need to be taken care of including between the teeth and that’s when different types of matrix bands and wedges need to be used. But for this specific filling there is no need to use any bands. Once all the decay has been removed the dentist will prepare the space for the filling by placing etch on the tooth.
Etch is an acid gel it’s usually blue colored and it’s used to roughen the surface of the enamel. Then the etch will be rinsed and suctioned and dried to prepare for the next step. So you’ll now notice that they’ve turned off the bright light. Because tooth colored fillings are actually hardened by light. This type of filling the composite filling.
This is a type of filling that is applied in layers and right now you’re watching the first step of the bonding agent. Where they brush it on to etch and prime the tooth. The next step is the adhesive which is light cured. So after brushing it on they will use the special light to harden it.
Now the tooth is one step closer to being ready for the composite. Also called the tooth colored filling or the resin. Now you could kind of see how fast this step is this one. I didn’t edit at all it just right it’s put in boom the composite. Actually putting the filling material in there takes one second. But the part that takes much more time is using the different instruments.
This instrument that the dentist is using to pack it and make it look like a tooth. So dentists will spend some time you know making it look good. They want to mold that composite filling that. They just placed in there to match the shape of the surrounding tooth.
So once the dentist is ready and happy with the shape after using multiple instruments to shape it. Then they will light cure it to harden it. There’s a fun different angle of the light curing step happening. So this filling in particular that you just watched is not in a spot. Where the patient would bite on it that surface of the tooth is not a spot that you bite. But for the blog’s sake we acted out the articulating paper step lastly. The dentist will finish the filling by polishing the final restoration.
So it’s nice and smooth and shiny. thank you all for reading please like and subscribe if you enjoyed this post and share it with your friends that love teeth.
