Cavity Fillings (Expectations, Types & Aftercare)

According to the American Dental Association (ADA), 91% of Americans over 20 have had cavities at some point in their lives, and 27% of people over 20 have untreated cavities!

If you’ve ever had a cavity, you know how uncomfortable it can be. Regular dental visits can uncover cavities before they become a pain.

There are many filling materials, and each is unique in function, composition, and utility.

What Type of Filling Material Is Best?

Fillings are essential to preserve the remaining tooth structure and prevent tooth fractures.

Some fillings are technique-sensitive (composite, inlays, onlays), while others are used when isolation is difficult (amalgam) or fluoride release is desired (glass ionomer). Isolation refers to keeping the tooth clean and free from saliva contamination during the filling process.

At times, adequate isolation is challenging; however, it’s essential for therapeutic success and longevity. Your dentist will review your options with you before treatment. But first, let’s compare the pros and cons of their most common filling materials.

What Are the Steps Involved?

First, the clinician will carefully remove the decayed tooth structure.

If the cavity is superficial, the clinician may remove the cavity without using an anesthetic, which is ideal for many reasons, including verifying the bite after correctly completing the restoration.

If anesthesia is necessary, the clinician will apply topical benzocaine, followed by an anesthetic.

After adequate anesthesia, the clinician will remove the cavity using a high-speed drill, followed by a slow-speed drill.

The slow-speed drill removes decay less aggressively to prevent trauma to the underlying pulp tissue.

Also, the clinician will have better control in removing the cavity without exposing the nerve.

The clinician may apply medication to prevent postoperative pain and future complications if the cavity is near the nerve.

This procedure is referred to as an indirect pulp cap. The dentist may use a direct pulp cap if the nerve is minimally exposed during decay removal.

A direct pulp cap technique is successful if isolation is maintained and minor trauma.

After removing the cavity, the area is irrigated and isolated to prepare the surface for proper bonding.

If the clinician uses amalgam or glass ionomer, the materials are prepared, applied, and allowed to set. If a composite resin is used, the area in the tooth is acid-etched, the dentist will apply the bond, and the dentist will use a light to set the material.

Then, the composite resin is layered in place and cured.

The clinician often overapply the material and polish it to an ideal size and shape. Finally, the bite and interproximal contact (contact with adjacent teeth) will be evaluated and adjusted.

Your clinician will ask you to bite down and grind your teeth adequately so high spots can be visualized and fixed before leaving the clinic.

Aftercare (Post-op) Instructions

Upon completion, the dentist will advise you to avoid eating until the anesthesia has worn off to prevent unnecessary tissue trauma.

The numbness should subside after a few hours. At that time, it’s normal for your teeth to be sore and tender. You should lightly massage your jaw muscles and apply a cold pack if needed. Also, your clinician may encourage you to take an NSAID to help heal.

Sensitivity with the restoration is possible for 1-2 weeks.

However, if you still feel discomfort, be sure to contact your clinician. You may be biting high on the restoration, and adjustments will be needed to eliminate the source of pain.

If dental pain begins to wake you up at night or the toothaches uncontrollably, you may have irreversible pulpitis, and a root canal may be recommended.

Considerations

Composite resin fillings are primarily used because of their versatility and availability. Inlays and onlays are best suited when the preparation size is too large for a predictable filling.

If the clinician is equipped with a scanning unit, they’ll be able to design, fabricate and deliver the restoration within a few hours. A full-coverage crown is avoided in this scenario, and the tooth structure is preserved.
