Cavities at gum line


Last Updated on July 18, 2022 by Dr Gustavo Assatourians DDS

Dental cavities are formed by the deposition of the sticky bacterial film called dental plaque on the tooth surfaces inside the oral cavity. The bacteria in dental plaque produce acids, which in turn dissolve the outer hard layer of the tooth called enamel. With increasing deposits and continuous microbial growth,first, a pit forms in the tooth, and then over time cavity develops. The roots of teeth are covered with a layer called cementum and are generally protected by gum tissue, but with the recession of gums, the root cementum will be exposed, becomes vulnerable in an oral environment ending up with gum line cavities. The root cementum is much weaker than the tooth enamel, so the cavities that form on the roots can get worse quickly. 

Causes of gum cavities and recession: 

Poor oral hygiene: Irregular brushing and flossing habits or aggressive brushing along the margins of gums and teeth.

Age: As the age advances, gums usually leave the tooth structure and recede below the margin of teeth.

Hereditary: It has been observed that gum diseases, periodontal issues, weak tooth structure, and recession in gums are common problems inherited from one generation to the next.

Habits: Smoking cigarettes or cigars, tobacco chewing, or any other kind of abusing substances, can lead to increased risk of gum diseases, weakening of teeth, dryness of mouth, and increased incidence of cavities.

Health problems and medications: Several health problems such as diabetes severely affect the architecture of gums causing weakening of the immune system and soft tissue inflammation, leading to more severe gum problems and recession. Some medications are also associated with dry mouth, which is one of the leading causesof the formation of dental caries and receding gums.  


  • Sensitivity to hot and cold due to the exposed root surfaces
  • A dull, constant groaning pain in the affected areas
  • Pain while chewing or biting
  • Inflammation and redness on the gums around affected areas
  • Weakness of teeth, causing cracks and fracture of the teeth
  • Discoloration of teeth
  • Recession of gum tissues


The treatment choice for the cavities in the gums depends upon the cause and severity of the lesion. Some common treatment options for gum cavities and receding gums include:

Periodontal therapy: If the cavities around the gum and tooth margin are formed due periodontal problems and gum recession, we start the treatment with our professional dental cleaning at our centre in Oxnard. Plaque and calculus removal from the root surfaces helps in reattachment of gingival soft tissue with the tooth structure reducing the risk of cavities around the gumline.

Soft tissue grafting: In cases of advanced gum recession, a minor surgical grafting of gum tissue helps in reattachment and reduction of cavities on the root surfaces

Dental fillings: If the tooth decay or cavity has already formed, the treatment involves restoring the affected areas with tooth-colored dental restorative materials to reduce the risk of extension of caries to the nerve tissue. 

Antibiotics: Systemic or topical antibiotics can also help in reducing the infection around the gum preventing spread of infection from marginal to the root surfaces.

Root canal treatment: In cases with nerve tissue involvement, root canal therapy is followed by a crown in the line of treatment for restoring the tooth structure. Here at Channel Islands Family Dental Office, dentist in Oxnard, we provide metal free tooth-colored porcelain and composite crowns to restore your healthy smiles.
