A cavity between teeth, also known as an interproximal cavity, can be tricky to spot because it often hides between your molars or premolars. Unlike cavities on the chewing surfaces, which are easily visible, interproximal cavities develop in the tight spaces where your teeth meet. This makes early detection crucial, as they can progress rapidly and become more extensive if left untreated.
What are the Signs of a Cavity Between Teeth?
Unfortunately, you can't always see a cavity between your teeth with the naked eye. Early-stage cavities are often invisible, making regular dental checkups essential. However, some signs might indicate a problem developing:
- Discoloration: You might notice a brown, black, or dark-grey stain between your teeth. This discoloration is often subtle and easily overlooked, but it's a potential early warning sign of decay.
- Sensitivity to Temperature: Sudden sharp pain when consuming hot or cold foods and drinks is a common symptom. This sensitivity indicates that the decay might be affecting the dentin, the layer beneath the enamel.
- Food Trapping: Noticeable food particles getting persistently stuck between certain teeth, especially after flossing, might indicate a cavity is forming. The cavity may be creating a small crevice where food can lodge.
- Swelling or Pain: In advanced stages, you might experience pain, tenderness, or swelling in the gums near the affected teeth. This suggests the cavity has progressed significantly and may have reached the pulp (the nerve of the tooth).
- Bad Breath: Persistent bad breath, despite good oral hygiene, could be a sign of a deeper cavity or infection.
How Can I Tell If I Have a Cavity Between My Teeth at Home?
While a professional examination is necessary for accurate diagnosis, you can perform a few self-checks:
- Careful Visual Inspection: Use a mirror and good lighting to examine your teeth. Look closely between your teeth for any discoloration or unusual crevices.
- Dental Floss: When flossing, pay close attention to any resistance or snagging feeling. If the floss repeatedly catches on a specific area between teeth, it could indicate a cavity.
- Interdental Brush: Using an interdental brush (small brush designed to clean between teeth) can help dislodge food particles and reveal potential areas of decay. However, this won't detect all cavities.
Important Note: Self-checks are not a substitute for professional dental examinations. These are merely tools to help you become more aware of your oral health.
What Happens If I Don't Treat a Cavity Between My Teeth?
Ignoring a cavity between your teeth allows the decay to progress. This can lead to several complications:
- Larger Cavities: The decay will continue to spread, requiring more extensive and potentially more complex dental procedures to repair.
- Tooth Abscess: The infection can reach the pulp, leading to a painful abscess, which requires immediate treatment to prevent further damage.
- Tooth Loss: In severe cases, the tooth may become so damaged that it needs extraction.
- Gum Disease: Untreated cavities can increase the risk of gum disease (periodontitis).
How Are Cavities Between Teeth Treated?
Treatment for cavities between teeth usually involves:
- Fillings: The decayed portion of the tooth is removed, and a filling material (composite resin, porcelain, amalgam) is used to restore the tooth's structure and function.
- Inlays/Onlays: For more extensive cavities, an inlay or onlay (a custom-made restoration) might be necessary.
- Crowns: If a substantial portion of the tooth is damaged, a crown may be placed to protect and restore the tooth.
- Root Canal: If the infection reaches the pulp, a root canal treatment may be necessary to remove the infected tissue and prevent further damage.
How Can I Prevent Cavities Between My Teeth?
Prevention is key to maintaining good oral health. Here are some essential steps:
- Regular Brushing and Flossing: Brush your teeth twice a day with fluoride toothpaste and floss daily to remove food particles and plaque from between your teeth.
- Mouthwash: Using a fluoride mouthwash can help strengthen tooth enamel and protect against decay.
- Regular Dental Checkups: Visit your dentist for regular checkups and professional cleanings. Early detection and treatment are crucial for preventing the progression of cavities.
- Healthy Diet: Limit sugary and acidic drinks and snacks.
- Dental Sealants: Consider dental sealants, especially for children and adolescents, to protect the chewing surfaces of their molars from decay.
