Dental decay can cause tooth nerve pain and lead to discomfort and sensitivity. Additionally, there are several other methods to kill tooth nerve pain faster, including over-the-counter pain relievers, topical numbing gels, or prescription medications. If these treatments do not provide relief, a dentist may perform a deep filling to restore the tooth’ structure and alleviate the pain.Typically, tooth filling is a minor procedure where dental materials are used to repair the damaged tooth structure and restore its functionality. The materials range from silver and gold to porcelain and composite. Well, how long it takes for the deep filling to settle down depends on the nature of the process, the material used, and the severity of the tooth cavity.

This dental procedure causes little pain and sensitivity, which resolves itself. Hence, it is expected to feel minor toothache after fillings. The discomfort reduces within one or two weeks, but it can sometimes continue and worsen the condition.

What Do You Experience After A Deep Tooth Filling?

Before answering the given title, let’ learn more about tooth filling! Fillings are a minor procedure that removes the decayed or damaged part of the tooth and replaces it with durable materials. The filling materials are molded in the tooth, which protects it from infection risks. Mostly, they are metal-based, resin, porcelain, and a combination. After a successful treatment, your tooth is saved and ready to function correctly again. The tooth pain you experience after the filling is normal and resolves without discomfort. Once the numbness, which was due to the effects of anesthesia given during the surgery, goes away, you may experience the following:

  • Toothache around the filling area when grinding down on your filled tooth.
  • Tooth sensitivity with sweet, hot, or cold foods or beverages that resolves itself.
  • Gum pain below the filling tooth.
  • Tooth sensitivity while brushing your tooth with a toothbrush.

Why Do Dental Fillings Cause Toothache?

Sometimes, most people feel a toothache after fillings. Many factors contribute to this discomfort, which unexpectedly comes and goes. Those include:

  • If you have chilled cold drinks, ice creams, or popsicles, you feel tooth pain after filling.
  • Sometimes, breathing through the mouth causes the cold air to hit your treated tooth, which can be painful.
  • Also, temperature sensitivity after a dental filling can be the cause that enables the tooth to handle hot drinks. Drinking coffee or tea following the treatment can lead to extreme pain.
  • Consuming sugary food items can also hurt your treated tooth, causing toothache.
  • Additionally, acidic foods and beverages can be unkind to your tooth.
  • The pressure of chewing down hard foods can also be terrible.

Why Do Dental Fillings Cause Tooth Sensitivity?

Tooth sensitivity after filling treatments does not occur out of the blue! Though it subsides over time, in some cases, tooth sensitivity following the filling needs an immediate cure. These are the possible reasons why your tooth hurts after the filling procedure:

1. Irritated Nerve

The deep filling is done when the cavity closely moves to the tooth nerve, causing severe toothache later. This pain is because of the deep filling that can upset the nerves inside your tooth. Typically, the tooth has an outer protective layer of cementum and enamel. It shields the tooth nerve from external factors. When it reaches the nerve, a deep filling irritates it and causes extreme inflammation. But as time passes, the nerve pain worsens, and sensitivity disappears. It would help if you had patience for some weeks. After completely recovering from the affected nerve, you will feel the filling tooth and surrounding teeth in good condition.

2. Incorrect Bite Alignment

It should be the crucial aspect of correct fitting that the placement of dental fillings must align perfectly with your bite alignment. If the material is not fitted correctly, it can significantly impact your biting pattern, leading to tooth sensitivity for some reasons. If the filling is above the tooth level, chewing the food can give extra pressure. This harsh force on filled teeth can lead to toothache and discomfort. Moreover, if you eat after the filling procedure, the chances of feeling some sensitivity are not expected. But your bite should self-correct after some weeks. If your filling doesn’t correct itself, it can increase sensitivity. Visiting a dentist can help file the fillings down.

3. Increased Pulpitis

Pulpitis is the inflammation when the dental pulp inside your tooth becomes inflamed. It can cause severe sensitivity and can hurt your tooth very severely. Undergoing a minor tooth filling may not lead to pulpitis, but you may experience it in some cases. You might feel inflamed pulp if your tooth suffers an injury, trauma, or accident that results in a broken or cracked tooth. The other reason can be the deep cavity that affects the inner layer of the pulp. And, sometimes, if the affected tooth has undergone several filling treatments before, it can lead to severe pulpitis. This dental problem can be restored effectively through root canal therapy.

How Long Does A Deep Filling Take To Settle Down?

Certain crucial factors contribute to how long it takes for deep filling to settle down after dental surgery. Those may include dental materials used, cavities severity, size of the hole, and so on. Typically, deep filling is done to fill a vast cavity when the hole in the affected tooth is deep and near the pulp. Moreover, the duration for deep filling to set will also rely on the material used to carry out the treatment. Clinical Trial says dentists usually recommend 24 hours for the filling to achieve the desired hardness and stability. When it comes to composite fillings, it instantly gets hardened following the UV light application.

On the other hand, amalgam fillings take almost 24 hours to settle down properly. Porcelain fillings are fixed within 24 hours after they are molded in your tooth. Remember to avoid biting the food on the side of the filling.
