Noticing a cracked filling can be concerning, as it often leads to pain and discomfort, especially when eating food. If left untreated, the pain can extend to the tooth itself, which may necessitate more complex treatments.

In this blog, we will explore some of the main causes of cracked dental fillings, their signs, and treatment options, so keep reading!

Common Causes of Cracked Fillings

Modern dental fillings are made of durable materials and can last a long time depending on material type and bite forces. However, like all other dental restorations, they may crack or fail at some point, especially with heavy bite forces or grinding. Common causes include:

  • Normal wear and tear: Over the years, routine pressure from chewing and biting forces can cause fillings to develop small cracks.
  • Chewing hard foods: If you frequently chew hard candies, nuts, or ice, it can put extra stress on fillings, sometimes causing cracks or small chips.
  • Dental injury: Falls or high-impact sports injuries can damage both your teeth and fillings.
  • Habits: Biting nails, pens, or other hard objects can wear off the filling material. This risk is also higher in patients with bruxism.
  • Size of the filling: Larger or older fillings, especially on the molars, are more prone to damage.

Signs You May Have a Cracked Filling

A small crack in a filling can be difficult to notice at first. However, you should seek immediate dental care if you observe any of these signs:

  • Tooth pain: Pain in a restored tooth, especially when chewing or biting, may indicate an issue with the filling.
  • Visible crack: In some cases, cracks or chips may be visible when you look at the tooth in a mirror.
  • Sensitivity: Cracks can expose inner tooth layers, causing increased sensitivity to hot or cold foods.
  • Sharp edges: A broken or cracked filling may leave rough edges that irritate your tongue or gums.

Can a Dentist Repair a Cracked Filling?

A filling cannot be repaired, rather, it is replaced if you visit your dentist at the right time. Taking prompt action is necessary to prevent further complications. If the damage is small and limited to the filling only (not involving the tooth), your dentist may simply replace the old filling with a new one.

In cases where the tooth and filling are severely damaged, a dental crown is recommended to protect the tooth. Your dentist may also perform a root canal before this procedure if the damage involves the pulp of the tooth.

Takeaway

Dealing with a cracked filling requires immediate action to prevent damage to the tooth. Even if the crack appears small at first, you should seek prompt care once you notice it or experience any discomfort.
