What Happens When You Get a Cavity Filled?

Almost everyone will have a cavity at some point in their lives. In fact, nearly 90% of adults have at least one cavity before age 60. Modern dental fillings can stop a cavity from progressing and restore a tooth with restorations that are nearly impossible to recognize. Wondering what happens when you get a cavity filled is a common question, especially for those with dental anxiety or parents who are wondering how their child’s cavity will be cared for.

Read on to learn what happens before, during, and after modern cavity treatment, and where to find the best dentists in Bedford and Windham for family dentistry. 

How Does a Dentist Know When a Filling is Necessary?

While early tooth decay can sometimes be stopped or reversed with fluoride before a cavity forms, most dentists recommend a dental filling when tooth decay has progressed enough to damage the enamel. Dental X-rays are the best way to see how far tooth decay has damaged a tooth below the surface. 

Early cavities often cause no symptoms, and waiting for pain can allow decay to progress deeper into the tooth. This is one of many reasons regular dental checkups are important even if you think your teeth and gums feel perfectly normal. 

What Happens During a Dental Filling?

After your dentist confirms an area of tooth decay, getting a filling starts by numbing the area around the tooth with a local anesthetic. This ensures you only feel pressure or movement during treatment, instead of sharp pain. 

The dentist then removes the decayed portion of the tooth and cleans the area so the filling can bond properly. Traditionally, a dental drill is used for this step. However, modern dentistry now uses dental lasers for faster, more precise treatment. 

After the decayed portion of the tooth is removed, the space is filled with a restorative material, which is shaped to restore the tooth's natural contours. Your bite is then checked to ensure your restored tooth feels comfortable when your teeth come together.

Are Tooth-Colored Fillings Better?

Tooth-colored composite fillings provide a natural-looking way to repair cavities. The material can be matched to the surrounding tooth and shaped to restore its normal appearance and function. Composite resin is increasingly used for dental fillings, especially when you want your dental work to blend into your smile. However, the choice of filling material depends on several factors, including the location and size of the cavity, the forces placed on the tooth during chewing, your oral health, and your personal preferences. 

What to Expect After Getting a Dental Filling

It is common for a newly restored tooth to feel slightly different for a short time. Additionally, your mouth may remain numb for several hours after local anesthetic. During this time, you should be extra careful when eating or drinking until normal sensation returns. Mild tooth sensitivity to temperature or pressure can occur after a filling, and usually settles as the tooth adjusts. 

When Does a Cavity Need More Than a Filling?

A filling works well when enough healthy tooth structure remains to support the restoration. More extensive tooth decay can weaken a tooth to the point that a dental crown becomes a better choice. If decay reaches the inner pulp and causes infection, root canal treatment may be needed to remove the infected tissue and preserve the tooth. In severe cases, a tooth extraction may be necessary.
