Good teeth mean enjoying every bite and staying in top shape. For people with diabetes, high blood sugar often leads to various oral health issues, affecting their ability to eat. Therefore, dental care is crucial for them, and scientific oral hygiene is essential.
Aim for blood sugar below 8.88 mmol/L before tooth extraction
Clinically, many diabetics with severe periodontitis delay tooth extraction due to concerns about diabetes and infection. This not only prolongs suffering but may also lead to serious complications. In fact, tooth extraction is feasible when blood sugar is controlled below 8.88 mmol/L and there are no symptoms of ketonuria or significant acidosis. However, the following precautions must be observed:
1. Avoid undergoing extraction on an empty stomach to prevent hypoglycemic coma during local anesthesia. For insulin-treated patients, schedule extraction 1–2 hours after breakfast when medication efficacy is optimal.
2. Minimize physical exertion before extraction to shorten procedure duration. For insulin-injected patients, complete extraction within two hours to prevent prolonged fasting and hypoglycemic reactions.
3. Use anti-infective medications before and after extraction. Due to impaired infection resistance, diabetic patients may experience prolonged healing, pain, or inflammation post-extraction. Follow medical advice to use antibiotics before and after the procedure to control infection and prevent dry socket.
4. Maintain emotional stability; sedatives may be administered before extraction if necessary.Patients with poorly controlled blood sugar or severe infections should consult an internist before extraction to determine if prophylactic antibiotics or other measures are needed to prevent infection at the site.
Dental implants require even greater caution for diabetics. Their reduced clotting function and slower wound healing mean that implant surgery—even minimally invasive—can lead to infection if not properly managed.Additionally, hyperglycemia negatively impacts osseointegration of implants, posing certain risks. Compared to healthy individuals, people with diabetes experience more rapid loss of alveolar ridge bone. Therefore, it is recommended that individuals with poorly controlled diabetes delay dental implant procedures until their condition stabilizes. This ensures personal safety and enhances implant success rates. Regular follow-up maintenance is also essential afterward.
Professional Teeth Cleaning: Seek Reputable Clinics, Avoid Excessive Procedures
Professional teeth cleaning is an effective method for managing periodontal disease in diabetics. However, many diabetics worry that the procedure may cause infections that affect blood sugar levels. Due to weakened immune systems, reduced phagocytic capacity of white blood cells, and microvascular complications leading to impaired microcirculation, improper cleaning techniques can easily result in infections.Additionally, the mechanical vibration or pain stimulus during scaling can increase secretion of glucagon and steroid hormones in diabetic patients, leading to insufficient plasma insulin and blood sugar fluctuations. Excessive scaling may also cause persistent gum bleeding, worsening or spreading infections, exacerbating complications, and worsening diabetes.
Therefore, it is strongly advised that individuals with diabetes avoid seeking cheap teeth cleaning at unregulated street clinics lacking strict sterilization protocols. Instead, they should visit accredited hospitals and consult professional dentists. Before the procedure, patients must disclose their diabetes history and provide recent blood glucose readings to the dentist, who will determine suitability for scaling. Strictly follow the dentist's instructions.
Use soft-bristled brushes and schedule regular check-ups every three months.
Beyond medical interventions, maintaining good oral hygiene habits in daily life is crucial for dental care in people with diabetes.
Brush frequently. Aim to brush and rinse before bed, after waking, and after every meal.
Brush gently. Soft-bristled brushes protect enamel and prevent periodontal pockets where bacteria can enter. Avoid excessive pressure and replace your toothbrush every 3-4 months.
Perform dental exercises.Each morning, perform 30 empty-mouth bites: the first 20 should be quick, impact-like bites, followed by 10 strong, sustained bites. This exercise strengthens chewing muscles, stimulates tooth roots and alveolar bone, and increases bone density around teeth.
Schedule regular dental checkups. Diabetic patients are advised to visit the dentist every three months to prevent diabetic periodontitis.
Gently massage gums. After brushing, use thumb and index finger to lightly massage both inner and outer gum surfaces—thumb on inner, index finger on outer—30 times per session. This promotes periodontal microcirculation and strengthens mucosal resistance.
Stay hydrated and maintain a light diet. Saliva prevents plaque buildup, washes away bacteria, and protects enamel. However, high blood sugar and certain oral hypoglycemic medications can cause dry mouth. To stimulate saliva production, people with diabetes can use fluoride toothpaste specifically designed for dry mouth. Drink plenty of water daily and avoid overly salty, sweet, or acidic foods, aiming for a light diet.
