If you have diabetes, your calendar is already full of lab draws, refills, eye exams and physician visits. The dental cleaning is often the one that slides to next month, then to next year.
You’re far from alone. According to the CDC, about 60% of US adults with diabetes had a medical visit in the past year but no dental visit. That gap matters, because diabetes and gum disease are linked.
November is National Diabetes Month, recognized by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), and World Diabetes Day falls on November 14. Our team put together a practical checklist for adults in McKinney, Allen, Frisco, Plano and Prosper: what to tell us, what we check, how often to come in and when to call.
For background on how gum inflammation and blood sugar connect, see our post on gum disease and whole-body health.
How Diabetes Can Show Up in Your Mouth
The CDC lists several ways diabetes can affect your teeth and gums. You may have less saliva, which leaves your mouth feeling dry. Your gums may become inflamed and bleed often, and infections in your mouth can take longer to heal.
The CDC also states that “gum disease can be more severe and take longer to heal if you have diabetes,” and that “if you have gum disease, your diabetes may be harder to manage.” Because the link runs both ways, your dental visits belong on the same list as the rest of your diabetes care.
According to CDC data, adults 20 and older with diabetes are 40% more likely to have untreated cavities than similar adults without diabetes. Adults 50 and older with diabetes have severe tooth loss, meaning 8 or fewer teeth, 56% more often than adults without diabetes.
Regular visits with a dental team that knows about your diabetes can help catch problems while they’re small.
Your Diabetes Dental Check-In Card
The CDC and NIDDK both advise telling your dentist that you have diabetes. NIDDK adds that you should share the medicines you take and any changes, such as rising blood glucose. Those details are easy to skip when you’re handed a clipboard and running five minutes late.
Copy this card into your phone’s notes app or onto an index card, and bring it to every visit:
| What to tell us | Why it matters |
|---|---|
| That you have diabetes or prediabetes | It helps us plan your exam and any treatment |
| Your full medication list, including insulin, GLP-1 medicines and anything else you take | NIDDK recommends sharing your medicines with your dentist |
| Any recent change in your blood sugar | NIDDK advises keeping your dentist updated on changes such as rising blood glucose |
| Your physician’s name | So our team knows who manages your diabetes care |
| Before a deep cleaning or extraction: your physician’s answers on blood glucose checks and medication timing | NIDDK advises asking your doctor these questions before oral surgery or extensive dental work |
If you take a GLP-1 medicine, our post on GLP-1 weight-loss drugs and your teeth covers mouth-related side effects.
What Happens at Your Cleaning and Exam
A cleaning visit at our office typically takes 45 to 60 minutes. Along with the cleaning, it includes a review of your health history, an exam, digital x-rays when they’re due and an oral cancer screening. Hand over your card during the health-history review.
As our professional dental cleanings page notes, “We’re often the first healthcare providers to notice early signs of conditions like diabetes.” If you already know you have diabetes, that same close look can help catch mouth changes early.
Good things to ask about during the visit:
- Your gums. Ask about bleeding, swelling or pockets that are deeper than at your last visit.
- Dry mouth. Tell us if your mouth feels dry, especially when you wake up.
- New cavities. Ask whether your exam or x-rays showed anything new.
- Sores and patches. Point out anything you’ve noticed, even if it doesn’t hurt.
How Often Should You Get Your Teeth Cleaned With Diabetes?
Dental care for diabetics uses the same cleanings and exams everyone gets, so the main question is timing. No single schedule fits everyone with diabetes, and the CDC suggests asking your dentist how often you should have your teeth checked.
Your schedule depends on what we find at your exam:
- If your gums are healthy, we’ll recommend a cleaning schedule at the end of your visit.
- If you’ve been treated for gum disease, we recommend periodontal maintenance every three months. This follow-up care is meant to keep the disease from coming back.
- If something changes between visits, such as gums that bleed most days or a sore that won’t heal, call us instead of waiting for your next cleaning.
Book your next visit before you leave, so it doesn’t slide.
If You Need a Deep Cleaning or Gum Treatment
Hearing “deep cleaning” can be unsettling when you’re already managing a chronic condition. Knowing what each treatment involves makes it easier to plan with your physician. Our gum disease treatment page lists the options we offer:
- Scaling and root planing. Our hygienists clean below the gumline to remove plaque, tartar and bacteria around the tooth roots. A deep cleaning needs local anesthesia and may take more than one appointment.
- Arestin. This antibiotic (minocycline) is placed in gum pockets 5 mm deep or more, usually right after scaling and root planing. Our Arestin page explains how it works.
- Laser therapy. We use Ezlase laser equipment for periodontal care, with no cutting or sutures. See our laser dentistry page for details.
- Osseous surgery. For advanced gum disease, our doctors remove infected gum tissue to reach the tooth roots.
The CDC notes that “treating gum disease may help lower your blood sugar over time.” Results differ from person to person, and gum treatment doesn’t replace the diabetes plan you follow with your physician.
Questions to Ask Your Physician Before Dental Work
According to NIDDK, high blood glucose raises the risk of infection after mouth surgery and can make your mouth take longer to heal. NIDDK advises telling your doctor before oral surgery or other extensive dental work and asking:
- How often should I check my blood glucose before and after the procedure?
- Should I change the dose or the timing of any of my medicines?
We suggest asking these questions before a deep cleaning or tooth extraction, too. Write the answers down and bring them to your appointment.
Your physician decides any changes to insulin or other diabetes medicines. Follow their instructions, and share them with us so our team has the full picture.
Mouth Signal to Next Step
Between visits, you’re the person most likely to notice a change. Use this table to decide how soon to reach us. It isn’t a diagnosis, so when you’re unsure, call.
| Mouth signal | What it can mean | Next step |
|---|---|---|
| Gums that bleed when you brush | Gum inflammation, which the CDC lists as a sign of gum disease | Call this week if it happens most days; otherwise mention it at your next cleaning |
| Dry mouth | Less saliva, which the CDC lists as a possible effect of diabetes | Mention it at your next cleaning, or call sooner if it’s new or uncomfortable |
| Painful white patches | Possibly thrush, a fungal infection NIDDK lists among diabetes-related mouth problems | Call this week |
| A sore that hasn’t healed in 2 weeks | Our office lists this among oral cancer warning signs, though it can have other causes | Call this week |
| Loose or shifting teeth | Possibly gum disease, since NIDDK lists loose teeth as a warning sign | Call this week |
| Slow healing after a procedure | High blood glucose can slow healing and raise infection risk, according to NIDDK | Call today |
For other causes of dry mouth, see our post on dry mouth after 50.
If a change doesn’t fit a row, call (972) 547-6453 and describe it. Our team will help you decide how soon to come in.
Helping a Parent Keep Up With Dental Care
If you help a parent manage diabetes, you know how many appointments that involves. Dental visits are often the first to drop.
A few habits help:
- Keep a copy of their check-in card on your phone, with the current medication list.
- Pair appointments. Book the dental cleaning in the same week or month as a physician visit.
- Pass along the physician’s answers before any deep cleaning or extraction.
- Watch for the signals in the table, especially bleeding gums, loose teeth or a sore that won’t heal.

Frequently Asked Questions
Q: Do I need to tell my dentist I have diabetes or prediabetes?
A: Yes. The CDC and NIDDK both advise telling your dentist about your diabetes, and NIDDK also recommends sharing your medicines and any changes, such as rising blood glucose. Mention prediabetes too, since it gives our team a fuller picture of your health.
Q: How often should someone with diabetes get a dental cleaning?
A: It depends on the health of your gums. The CDC suggests asking your dentist how often you should have your teeth checked, and we’ll recommend a schedule after your exam. If you’ve been treated for gum disease, we recommend periodontal maintenance every three months.
Q: Should I check my blood sugar before a deep cleaning or tooth extraction?
A: Ask your physician. NIDDK advises talking with your doctor before oral surgery or extensive dental work about how often to check your blood glucose before and after, and whether to change the dose or timing of any medicine. Follow your physician’s instructions and tell our team what they advised.
Q: Can treating gum disease help my blood sugar?
A: It may. The CDC states that “treating gum disease may help lower your blood sugar over time.” Results differ from person to person, and gum treatment doesn’t replace your diabetes care plan, so keep following your physician’s guidance.
