Does Getting a Cavity Filled Hurt?

Cavities are quite common, even for those who have excellent oral hygiene. When a cavity happens, the dentist will remove the decaying portion of the tooth and fill the area with a strong material that will seal the hole. Without the filling process, the cavity will get much worse, and can lead to pain, abscess or even bone loss. Even so, many people avoid getting cavities filled because they are afraid of the dentist. Then does this procedure really hurt?

Does Getting a Cavity Filled Hurt?

No, it usually does not hurt. Many people are terrified of going to the dentist because they hate the idea of pain. However, it’s important to remember that a dentist will never deliberately cause pain, and if you feel pain during any procedure, it’s best to make it clear immediately so that steps can be taken to remedy the problem. For getting a cavity filled, dentists will use a local anesthetic to numb the area. They numb the area with an injection in your gums; if that frightens you, most dentists will offer a numbing gel to use before the shot to ease the pain of it. Once the injection is done, you might feel pressure from the instruments used, but no pain.

How Is a Cavity Filled?

In order to fill a cavity, the dentist will first use the local anesthetic. After that, a specific tool will be used to remove the damaged area of the tooth. This is usually done with a small drill, air abrasion instrument or laser – it depends on your preference, the expertise of the dentist as well as the area where the cavity is located. The dentist might test the area several times during the process to ensure all the bad area is removed.

Next, the dentist will clean the debris and bacteria extremely well. As part of this process, the doctor might put a barrier of resin, glass ionomer or other material to protect the nerve. Does getting a cavity filled hurt if the nerve is exposed? That’s possible – which is why dentists are so careful with ensuring the root is protected.

The dentist will then insert a filling that adheres to the healthy teeth and fill in the hole. This is usually done in layers; a special light is used to harden the area after each layer is applied. When it’s all complete, the filling will be filed down and polished.

Note: Please remember that there is almost no risk at all when a cavity is filled – it is a very common and safe procedure. If you have heart problems, let your dentist know so antibiotics can be given before the filling is done. This is because bacteria might enter the bloodstream and cause infection among those who have weakened immune systems or issues with their heart. The antibiotics lower the risk of endocarditis and other complications.

How to Care for the Cavity Filling

Now you know the answer to “does getting a cavity filled hurt?” Then what about after the procedure is done? In the first 1-3 hours, your mouth will be still numb. Don’t try to bite or chew now because you might end hurting your tongue or lips. This is especially important for children, because they may find the numbness very interesting and want to play with it. Once the anesthesia is gone, the area around the filling might be a bit sore, especially if the dentist had to remove areas that are below the gum line. This soreness will go away within a few days.

Here are some tips to help you care for the cavity filling.

  • If the sensitivity or pain around the filling doesn’t go away in a week, call your dentist.
  • If your filling is silver, don’t chew on the new filling for at least 24 hours. If it is a white filling, it is okay to eat normally once the numbness is gone.
  • When you do eat, check to ensure that your teeth do not grind together at the filling area. If they do, you will need to go back to the dentist to have the filling filed down a bit more.
  • A ‘deep’ filling, one that reaches down to the root, might cause a bit more pain than other types. Sometimes this type of filling does not work, and the root will die. In that case, you might not feel any pain at all, but you will eventually need a root canal to save the tooth.
  • Regularly brush or floss your teeth. Try to take tooth-friendly diet, such as less sugar.
  • Some drinks, such as coffee, red wine or tea, can cause staining on both your natural teeth and the filling. Though it can be polished away, over time the buildup can become severe, so it is best to cut down on your consumption of these products.
  • When you smoke, a yellowing of the white filling is a common problem. This is very noticeable. Avoid smoking to keep your teeth looking good (and your overall health much better).
  • Sometimes a filling will crack or ‘leak’ a bit. Consult your dentist in this case. He/she will take x-rays to assess the condition.
  • Sometimes fillings will wear out, and they will need replacement. Does getting a cavity filled hurt when you are simply replacing the filling? Though some anesthesia might be required, there is probably no drilling, which will make the entire process much easier.
  • Get a regular checkup every six months. This includes a full inspection of your teeth as well as a thorough cleaning.
