What Do Fillings Fix?
If you have been feeling some discomfort when chewing, you may have a cavity forming. The key to fixing cavities is to get them filled while they’re still small. Small cavities can be filled in about an hour, but larger cavities may take a little bit longer. What’s even better than fixing a cavity while it’s small is not ever getting the cavity to begin with! Cavities are the most common problem that dental fillings fix.
You may be wondering how you even got a cavity because you brush and floss twice a day and visit your Anchorage dentist every six months. While most cavities result from ineffective oral hygiene, the science behind cavity development shows that there are powers at work in our mouths that may be beyond our control.
Enamel is the strongest, most mineralized substance in the human body; enamel is also very porous. Dentin is under the enamel and is made of microscopic tubules that extend into the middle of the tooth; dentin is even more porous than enamel. When a substance is porous, it has tiny spaces or holes in which substances can pass.
When oral bacteria get through the enamel of the teeth and reach the dentin, tooth decay with cavities develops. In that case, your general dentist in Anchorage will have to fix the cavity with a dental filling. X-rays provide your dentist with a clear view of the cavity; in some cases, digital scans of the teeth may be necessary.
New dental fillings may be needed to fix old fillings made of metal (amalgam). Advanced technology allows your restorative dentist in Anchorage to place tooth-colored fillings using ultrasonic technology, ensuring your new fillings last much longer than the metal fillings of yesteryear.
