What Causes a Small Scratch or Groove on a Tooth and What to Do?

A small scratch or groove on your tooth that is about 1mm deep can be caused by several factors. Understanding the causes can help you determine the best course of action if you notice such a mark on your tooth. Here are some common causes and what could be behind them:

Causes of a Small Scratch or Groove

Mechanical Wear: This can occur from aggressive brushing using a hard-bristled toothbrush or grinding your teeth, a condition known as bruxism. Over time, this can lead to the formation of small scratches or grooves on your tooth enamel.

Dental Erosion: Acidic foods and drinks such as citrus fruits, sodas, and wine can erode the enamel on your teeth, creating grooves over time. This process can be gradual and may not be immediately noticeable.

Cavities: Early-stage tooth decay can appear as small grooves or scratches on the surface of a tooth. These may be indicative of a developing cavity that needs to be addressed before it worsens.

Trauma: An injury to the mouth, such as a fall or a sports-related trauma, can cause scratches or grooves on your teeth. Even micro-traumas that you might not notice, like hitting your teeth against a hard object in your sleep, can leave marks over time.

Dental Procedures: Previous dental work such as fillings or crowns can sometimes lead to changes in the surface of your tooth. If a filling has shifted or worn down, it can create a groove or a scratch.

What to Do if You Have a Small Scratch or Groove

It's advisable to consult a dentist for a proper diagnosis and treatment options, especially if you are experiencing sensitivity or pain from the scratch or groove.

If you have broken a front tooth on a piece of toast or scrambled eggs, it's crucial to seek dental care. Teeth can break due to wear and tear, trauma, or even dental procedures that might have led to changes in the tooth's structure. Here are some steps to follow:

Don't Panic: Most small chips, though they may feel uncomfortable, do not cause major problems. Sensitivity to temperature is common and can be managed with desensitizing toothpaste. Keep It Clean: Brush and floss even if a tooth is broken or decayed. This is important to maintain oral health and prevent further complications. Use Desensitizing Toothpaste: If the tooth is sensitive to temperature changes, applying desensitizing toothpaste can help. You can use it whenever you feel like it and especially at night before bed. Consult a Dentist: Even if you are in lockdown or quarantine, contact your dentist for advice if the situation worsens. They can provide specific recommendations and treatment options.

Remember, understanding the cause of a tooth scratch or groove can help you manage it effectively. Regular dental check-ups and good oral hygiene practices are key to maintaining the health of your teeth and preventing issues before they become more serious.
