Q: Is It Normal for Dental Floss to Reach Deep into Gum Pockets?

Hello Ms. <br>Hsu： The ability to place dental floss deeper into the gingival sulcus may indicate the presence of periodontal pockets. <br>It is recommended to consult a dentist for examination and necessary treatment. <br>Dr. <br>Tseng Guang-Hui, Department of Dentistry, Nantou

Dental floss can be inserted deep into the gingival sulcus?

Hello, Doctor.
I just used dental floss while looking in the mirror and accidentally discovered that I can insert the floss quite deeply between my teeth (if viewed from the front, the gums form a flat U-shape, and the floss can slide in from the side almost halfway into the U).
The floss doesn't feel like it's being forced in; it slides in quite naturally.
I have checked, and normal periodontal pockets should be less than 3mm, so is it normal for me to be able to insert the floss this deeply (it appears to exceed 3mm)? I usually brush and floss immediately after eating, and I don't experience any bleeding or pain while brushing or flossing, and there doesn't seem to be any significant redness or swelling.
I had a dental cleaning last month, and the dentist didn't mention anything in particular.
However, prior to this year, I hadn't seen a dentist or had a cleaning for several years, and I'm a bit concerned that I might actually have periodontal issues.
Should I schedule an appointment for an examination? Thank you.

It is understandable to be concerned about the depth to which dental floss can reach into your gum pockets. The normal depth of periodontal pockets is indeed less than 3mm, and if you are able to insert dental floss deeper than this without any pain or bleeding, it may indicate the presence of a periodontal pocket or gum disease.
When you use dental floss and it glides easily into the space between your teeth and gums, it can suggest that there may be some loss of attachment of the gum tissue to the tooth, which is a hallmark of periodontal disease. Healthy gums should not allow dental floss to penetrate deeply into the gum line. The fact that you do not experience bleeding or pain is a positive sign, but it does not completely rule out the possibility of underlying issues.

Given your history of not visiting a dentist for several years, it is advisable to schedule a dental check-up. A dental professional can perform a thorough examination, including measuring the depth of your gum pockets and assessing the overall health of your gums and teeth. Regular dental visits are crucial for early detection and treatment of potential periodontal issues, especially since you mentioned that you had not seen a dentist for a significant period before your last visit.

In addition to professional evaluation, maintaining good oral hygiene practices is essential. Brushing your teeth at least twice a day and using dental floss daily can help prevent the progression of gum disease. If you notice any changes in your gums, such as increased swelling, redness, or bleeding, it is important to seek dental care promptly.

Furthermore, if you have been experiencing any unusual symptoms, such as persistent bad breath, it could be related to the health of your teeth and gums. Bad breath can often be a sign of gum disease or tooth decay, both of which require professional intervention.
In summary, while it may not be entirely unusual for dental floss to reach deeper into gum pockets, it is not a sign of healthy gums. Given your dental history and the observations you've made, I strongly recommend that you consult with a dentist for a comprehensive evaluation. Early intervention can prevent more serious complications and help maintain your oral health.
