A number of patients have wondered why their fillings, inlays, onlays, or dental crowns have been causing them pain. There are a few different answers to that. Let's consider tooth sensitivity and toothaches related to your dental restorations and what can be done about this issue.

The Anatomy of a Tooth

To understand how dental restorations can lead to tooth sensitivity, it's important to first consider the general anatomy of a tooth.

There are three layers to a tooth. The topmost layer of a tooth is comprised of enamel, which is one of the hardest substances in the human body. The underlying layer is comprised of dentin, which is porous; these pores are known as dentinal tubules. Inside of a tooth is a hollow chamber that is filled with dental pulp. The dental pulp is comprised of blood vessels, nerves, and connective tissue that were all essential for the initial formation of the tooth.

How Tooth Sensitivity Occurs

While the causes can vary, the reason that tooth sensitivity and pain occurs in this context involves breach of the enamel. When the enamel is bypassed, pressure, hot temperatures, and cold temperatures can access the dentin. Since the dentin is porous and linked to the dental pulp, it is far more sensitive than the enamel.

Below are just a few ways that your fillings, inlays, onlays, and crowns can contribute to tooth sensitivity.

Adjusting to New Dental Fillings and Crowns

When you get a new dental restoration, it can take a little time to get used to it. It's not uncommon for people to experience tooth sensitivity for the first few days after getting new restorations placed. In many cases, this is just a temporary side effect of the restoration process.

Poor Fit from Dental Fillings and Crowns

If you get a dental restoration that isn't properly fitted, it can lead to serious issues with pressure on the teeth. Biting and chewing may be the source of great discomfort. Even soft foods may give your trouble if the restoration is pressing into the enamel and dentin in an awkward way.

Worn Down Dental Restorations

While dental restorations are strong, they are susceptible to wear and tear over time. Many restorations will need to be replaced after about 10 to 15 years. If you start experiencing sensitivity around an old restoration, you may be due for a new one.

Decay or Damage Around a Dental Restoration

In certain cases your dental restorations may be just fine, but there's been decay, chips, or cracks around it. This can lead to major issues with sensitivity, and the restoration should be fixed or refitted in order to prevent soreness and pain.

Treatments for Pain Related to Dental Restorations

The best treatment for pain and sensitivity caused by dental restorations typically involves replacing or repairing the restorations in question. This could mean new fillings, inlays, onlays, or crowns, or it may mean patching and fixing what's there. The best way to learn about all of these options is to stop by the practice for a consultation.
