Why Did My Teeth Gaps Widen After Removing Tartar? - Dentistry

Regarding interdental spaces?


Hello Doctor, I would like to ask about my four front teeth in the middle.
For the past six months, I often went to bed without brushing my teeth due to certain reasons, which led to a significant buildup of tartar between these four teeth.
There was originally not much space between them, but I noticed that after getting a dental cleaning today, the gaps between these teeth suddenly became quite large (it feels like those gaps were filled with tartar).
This is especially noticeable with the two central incisors.
Could you please explain why this happened? Thank you very much!

Hello: Due to long-term pressure from dental calculus on the gums, gum recession has occurred, resulting in enlarged spaces between the teeth.
Therefore, after the removal of the dental calculus, the gaps may appear particularly noticeable.
It is recommended to observe the situation, maintain cleanliness, and gradually the gums may return to their original height.
If it remains unacceptable and affects your mood and daily life, you may consider undergoing gum contouring surgery (out-of-pocket expense/periodontics).

More Info


When you remove tartar from your teeth, it can sometimes lead to the appearance of larger gaps between your teeth, especially if there was a significant buildup of tartar that was previously filling those spaces. Tartar, or calculus, is hardened plaque that forms on the teeth and can create a false sense of tightness between teeth. When it is removed, the natural spacing that was previously obscured becomes visible, leading to the perception that your teeth gaps have widened.

There are several reasons why this phenomenon occurs:
1. Natural Tooth Alignment: Over time, teeth can shift slightly due to various factors, including the presence of tartar. When tartar is removed, the teeth may settle back into their natural alignment, which can create or reveal gaps that were previously not noticeable.

2. Gum Recession: If you have experienced gum recession, which can be exacerbated by poor oral hygiene, the gums may pull away from the teeth, leading to increased gaps. Tartar removal can sometimes highlight this recession, making the gaps appear larger.

3. Loss of Support: Tartar can provide a certain level of support to the teeth. Once it is removed, the teeth may feel less stable, and any existing gaps may become more pronounced.

4. Changes in Oral Hygiene: After tartar removal, if you continue to maintain good oral hygiene, your gums may begin to heal and tighten around the teeth. This can sometimes lead to a temporary appearance of larger gaps as the gums adjust.

To address your concerns about the widening gaps, here are some recommendations:
1. Maintain Good Oral Hygiene: Continue brushing your teeth at least twice a day and flossing daily. This will help prevent the buildup of plaque and tartar, which can exacerbate the issue.

2. Regular Dental Check-ups: Schedule regular visits to your dentist for cleanings and check-ups. Your dentist can monitor your gum health and tooth alignment, and they can provide professional advice tailored to your specific situation.

3. Consider Orthodontic Evaluation: If the gaps are significant and concerning, you may want to consult an orthodontist. They can evaluate your teeth and determine if any orthodontic treatment is necessary to close the gaps or align your teeth properly.

4. Gum Health: If you suspect gum recession or other gum issues, discuss this with your dentist. They may recommend treatments to improve gum health, such as scaling and root planing or other periodontal therapies.

5. Diet and Lifestyle: Pay attention to your diet and lifestyle choices that may affect your oral health. Reducing sugary foods and drinks, quitting smoking, and managing stress can all contribute to better gum and tooth health.

In summary, the widening of gaps between your teeth after tartar removal is a common occurrence and can be attributed to the removal of the tartar that was previously filling those spaces. By maintaining good oral hygiene and consulting with your dentist, you can manage this issue effectively and ensure the long-term health of your teeth and gums.
