Frequently Asked Questions

The elevated blood sugar levels resulting fromdiabetescan make it hard to maintain oral health. As a result, people with this condition are more prone togingivitisandperiodontitis(types of gum disease),halitosis(chronic bad breath), loss of teeth, dry mouth, and oralthrush(a fungal infection).

This article explores the connection between diabetes and oral health, associated dental issues, and what you can do to prevent them.

Managing and Preventing Complications of Diabetes

The Connection Between Diabetes and Oral Health

Diabetes can increase the chances of developing certain oral problems in several ways.

High glucose(sugar) in the blood also causes increased levels of sugar in saliva. The bacteria in plaque, the sticky film that builds up on teeth, feed on these sugars, which can cause tooth decay, cavities, and tooth loss, as well as raise the risk of periodontitis (gum disease).

Furthermore,diabetes weakens the immune system, making it more difficult for infections to heal and to manage issues in the mouth. This, too, raises the risk of periodontitis and affects healing.

Lastly, insufficient saliva production can be a side effect of certain diabetes medications. When your mouth is too dry, it’s less able to clear food particles from the mouth and stop bacteria from forming plaque, increasing the risk of tooth decay, cavities, and tooth loss.

Types of Diabetes

Diabetes refers to multiple conditions impacting the body’s ability to break down sugars for energy. Most commonly, people havetype 2 diabetes, in which there is insufficient uptake of glucose in cells causing an increased but inadequate production of insulin, the hormone that regulates blood glucose levels.

Oral Health Problems Associated with Diabetes

Diabetes can lead to and raise the risk of various dental health problems. Here are the most common issues people with diabetes should be aware of.

Dry Mouth

In addition, since saliva plays a role in controlling bacterial spread in the mouth, a dry mouth raises the risk of gum diseases, cavities, tooth decay, and tooth loss.

Tooth Decay

Tooth decayfrequently accompanies diabetes. High glucose in the bloodstream increases the sugars in saliva, which feed the bacteria in the mouth. As a result, the level of acidity rises, which breaks down the hard enamel shells of the teeth. In turn, tooth decay leads to cavities and, if untreated, tooth loss.

Tooth Loss as a Risk FactorTooth lossis much more common among people with diabetes than the population as a whole. In fact, people with diabetes can experience nearly twice as many missing teeth.

Gingivitis

Proper dental care and healthy habits can cure gingivitis, but if left untreated, it can cause more severe infections (periodontitis), tooth decay, bad breath, and other issues.

Periodontitis

Periodontitis is a severe gum infection and a complication of gingivitis. In addition to bleeding and swelling in the gums, this disease can cause pockets (known as abscesses) to form around the roots of teeth and surrounding bone. This can lead to loose teeth, chewing difficulties, and chronic bad breath and can damage underlying bone leading to tooth loss if it isn’t managed.

Because high blood glucose also impacts the immune system, gum diseases, like periodontitis and gingivitis, are tougher to manage.

Thrush

Slow Wound Healing

Reduced immune function commonly accompanies diabetes, which can impact the mouth’s health. When blood glucose levels are high and insulin is too low—common features of this condition—the body cannot produce enoughcytokines.

These proteins and lipids (fats) are essential for immune system signaling and function. In addition, diabetes hinders leukocytes (a blood cell that combats infection) and decreases the immune system’s ability to recognize attacking bacteria, viruses, or fungi.

As a result, wound healing is hampered in those with diabetes. This makes it easier for gum disease to develop into periodontitis and allows cases to become more severe. This increases the chances of developing oral health problems like tooth decay and loss.

Preventing Dental Issues

Given the close association between diabetes and oral health problems, dental care is critical if you have diabetes. Several strategies can help prevent issues from arising, including:

Summary

Among the many negative health impacts of diabetes is poor oral health. This disease can lead to gingivitis and periodontitis, tooth decay and loss, dry mouth, and oral thrush (a fungal infection on the tongue or inside of the mouth). In addition, oral problems can worsen because of diabetes' impact on immune system function.

Managing blood sugar levels, attending timely dental visits, adopting good oral hygiene habits, and quitting smoking can help prevent oral health problems from arising.

A Word From Verywell

While protecting oral health may not be the primary focus of diabetes management, it’s an essential part of diabetes care. Dental issues raise the risk of developing more severe health conditions and can significantly impact your quality of life and confidence. If you have diabetes, be proactive: Seek treatment and talk to your dentist about what you can do to preserve your smile.

Frequently Asked QuestionsYes. Diabetes can significantly impact your oral health. This disease raises the risk for periodontitis (severe gum disease) and dry mouth and can cause saliva to have high sugar content.This damages teeth health, increasing the risk of cavities, tooth decay, and, if left untreated, tooth loss.Learn MoreThe Connection Between Diabetes and Periodontal DiseaseIt depends. Gum disease ranges in severity. Gingivitis, a milder, earlier-stage gum disease, is relatively harmless and can be reversed with a professional cleaning and good oral health habits.However, if gingivitis goes untreated, a more severe form, periodontitis or periodontal disease, arises. In these cases, the gums become infected and start to pull away from the teeth and bone, raising the risk of tooth loss. Periodontal disease can also be managed, though it requires more extensive dental treatment.Learn MoreUnderstanding PeriodontitisIf you have diabetes, let your dentist know, as this disease can seriously impact oral health. Your dentist will tell you how often you should get cleanings and treatments. In general, it’s recommended that you have dental appointments at least once every six months if you have diabetes.Learn MoreManaging Diabetes: What You Should Know
