Proximal Caries (Cavities Between Teeth) – Radiograph X-rays, Treatment, Restoration, Classification

Key Facts

• Proximal Caries are cavities that develop in the proximal surfaces of the teeth, which are the surfaces adjacent to each other
• These cavities often start as minor demineralization of the tooth enamel but can progress into larger cavities
• Proximal Caries are harder to detect in the early stages because they are hidden between teeth
• Dental X-rays are often the most effective way to detect them
• The primary cause is poor oral hygiene (especially infrequent flossing), but diet and genetics can play a role
• Early detection and treatment are key to preventing extensive tooth damage

What are Cavities between Teeth?

Cavities, or dental caries, are permanently damaged areas on the hard surface of the teeth that develop into holes or openings. Proximal caries, specifically, occur on the surfaces of the teeth that are adjacent to each other. This area, being difficult to clean with regular tooth brushing, becomes a prime location for plaque accumulation. Bacteria in the plaque produce acids which, over time, demineralize the tooth enamel and can cause cavities.

How do I Know that I Have a Cavity Between My Teeth?

Detecting Proximal Caries can be challenging due to their location.
However, there are some signs and symptoms that can indicate their presence:

• Tooth Sensitivity: An increased sensitivity to hot, cold, or sweet foods and drinks.
• Floss Shredding: If your dental floss frequently tears or shreds when flossing a specific area.
• Pain When Biting Down: Feeling pain or discomfort when biting down can be a sign of cavities between teeth.
• Visible Holes or Dark Spots: In more advanced stages, you may see dark spots or holes between teeth.

Because early-stage proximal caries are difficult to detect visually, regular dental check-ups and x-rays are essential for early detection.

What Do I Do if I Have an Interproximal Cavity?

If you suspect or know that you have a cavity between your teeth, it is important to take action:

• Consult Your Dentist: Make an appointment with your dentist as soon as possible. Describe the symptoms you are experiencing.
• Undergo a Dental Examination: Your dentist will likely take dental X-rays, which are particularly effective in revealing cavities between teeth.
• Follow the Recommended Treatment Plan: Depending on the severity of the cavity, your dentist may recommend different treatments:
  • Resin Infiltration: For incipient decay non-invasive procedures like DMG Icon resin infiltration may be applicable.
  • Filling: For smaller cavities, the dentist may remove the decay and fill the hole with a filling material.
  • Crown: For larger cavities, a crown might be needed to restore the tooth.
  • Root Canal: If the cavity has reached the tooth’s pulp, a root canal may be necessary.
• Improve Oral Hygiene: Brush your teeth twice a day, floss daily, and consider using an antiseptic mouthwash. Reduce sugary foods and drinks.
• Follow-up: Attend all follow-up appointments to ensure the cavity is properly treated and doesn’t progress.

How do I Prevent a Cavity Between Teeth?

Preventing proximal caries involves a combination of good oral hygiene practices and regular dental check-ups:

• Brush Regularly: Brush your teeth at least twice a day with fluoride toothpaste to remove plaque and food particles.
• Floss Daily: Use dental floss to clean between your teeth daily. This is especially important for preventing cavities in proximal areas, which your toothbrush might not reach.
• Use Mouthwash: Use an antibacterial mouthwash to help reduce the bacteria that can cause cavities.
• Eat a Balanced Diet: Limit sugary and starchy foods and drinks, as these can contribute to tooth decay. Eat a balanced diet with plenty of fruits, vegetables, and dairy products.
• Drink Water: Drinking water, especially fluoridated water, can help rinse away food particles and bacteria and can promote remineralization.
• Regular Dental Check-ups: See your dentist for regular check-ups and cleanings. This will ensure that any signs of cavities or other dental issues are caught early.
• Dental Sealants: Talk to your dentist about applying dental sealants. These can be especially helpful in protecting the nooks and crannies in your teeth where food particles can get trapped.
  

  Why Dental Fillings in Proximal Areas are Less Durable?

  Dental fillings in the proximal areas tend to be less durable for a number of reasons:

  • Constant Pressure: The sides of our teeth are subject to constant pressure from chewing and biting, which can cause wear and tear on the filling material over time.
  • Difficulty in Placement: Because of the location, placing a filling in between teeth can be more difficult. This makes it harder to create a perfect seal, and the filling might be more prone to leakage and recurrent decay.
  • Moisture Control: Keeping the area dry during the filling process is more challenging in proximal areas. Moisture can compromise the bond between the tooth and the filling material.
  • Material Used: The material used for the filling may not be as durable as other options, especially in the high-pressure environment between teeth.

  Bottom Line

  Proximal caries are cavities that form in the spaces between teeth and can lead to extensive tooth damage if left untreated. The hidden nature of these cavities means that regular dental check-ups and X-rays are crucial for early detection. If you suspect you have a cavity between your teeth, consult your dentist to receive proper assessment and treatment. Dental fillings in proximal areas might be less durable due to the challenges associated with their placement and the constant pressure from chewing. It is important to follow a dentist’s recommendations for care and maintenance of fillings and overall oral health to protect against cavities and ensure the longevity of dental work.
