Is It Time for a Dental Filling? Signs You Need One

Man getting a dental filling

One treatment many patients get is a tooth-colored filling. This is an effective restorative service that helps repair damage and decay, but when would someone need one? You might wonder how you can tell, but thankfully, it can be as easy as familiarizing yourself with a couple of symptoms. Here are the signs you need to know and what happens when getting a filling.

How Can I Tell If I Need a Dental Filling?

As was mentioned above, a reason you’ll need this restorative treatment is if you have a cavity. You can develop this oral health issue because of the bacteria in your mouth. They produce an enamel-dissolving acid, which can expose the dentin underneath. When this happens, you may notice:

  • A persistent toothache
  • A noticeable dark spot on your tooth
  • Discomfort as you bite and chew
  • Sensitivity to hot, cold, and overly sweet foods and drinks.
  • Floss that snags against a particular tooth

You may also need this service if you have minor damage. Getting one can help close the space that was created, protecting the inner dental structures and giving you back the function of the tooth. If you also had an old filling break or come out, then you’ll need to replace it to avoid any problems.

What Happens During a Filling?

With that being said, if you suspect you need a filling, you may be a bit curious about what you can expect to happen while you get one. Thankfully, it’s an easy process that you shouldn’t be worried about. Your dentist will start out by taking an X-ray and doing an oral examination to see the extent of the decay or damage. If it’s minor, then a filling can be what you need, but more major ones may need another service.

Afterward, your provider will remove the damaged parts of your tooth. They’ll fill these places with a composite resin and cure it with a special light. Then you’re all set! Your final restoration will blend in since it was color-matched to your smile, so you don’t have to worry about it looking obvious.

In the end, keep in mind the signs above that tell you that you need a filling. Getting this treatment as soon as you notice them can help you enjoy this minor service. That way, you don’t need a crown or anything else to get back to a problem-free smile you love.
