How Often Should You Get Your Teeth Cleaned?
Most adults with healthy gums, no chronic health conditions, and a consistent home routine need a professional cleaning every six months. People with gum disease, diabetes, a history of frequent cavities, or who smoke may be advised to come every three to four months instead. Plaque can begin hardening into tartar within 24 to 72 hours, and once tartar forms, brushing alone cannot remove it.

“You should come back in six months.” If you've ever sat in a dental chair, you've heard that line. The twice-a-year dental cleaninghas become so ingrained that most people assume it's a universal rule. But is it really the right interval for everyone?
The short answer is: it depends. Your ideal cleaning schedule is shaped by your gum health, medical history, lifestyle habits, and how effectively you care for your teeth at home. At Orion Dental in Scarborough and Milton, we work with each patient to determine the cleaning frequency that makes the most sense for their situation.

Where the Twice-a-Year Rule Comes From
The six-month cleaning recommendation was originally designed for the average, healthy adult — someone who does not smoke, has no chronic health conditions, brushes and flosses consistently, and has no history of gum disease. For this group, two professional cleanings per year is generally sufficient to remove tartar buildup and catch small issues before they become larger problems.
However, not everyone fits the “average” profile. Individual risk assessment is what should guide cleaning frequency, rather than a one-size-fits-all timetable. Your dentist considers factors such as pocket depths, bleeding on probing, tartar accumulation rates, and your overall systemic health when recommending a schedule.
Did You Know?
Plaque can begin hardening into tartar within 24 to 72 hours if not removed. Once tartar forms, it cannot be removed with brushing alone — only a professional cleaning can eliminate it.
Who Should Stick to Twice a Year
If the following describes you, a cleaning every six months is likely appropriate:
Good Candidates for Six-Month Cleanings
- No history of gum disease or periodontal treatment
- Consistent daily brushing (twice a day) and flossing
- No chronic health conditions such as diabetes or cardiovascular disease
- Non-smoker with no tobacco use
- No medications that cause dry mouth or gum changes
- Minimal tartar buildup between visits
Children should also visit the dentist every six months, starting from their first birthday or within six months of their first tooth erupting. Our children's dentistry team monitors the development of primary and permanent teeth, applies dental sealants when appropriate, and establishes a foundation of positive dental habits.
Who May Need Cleanings Every 3 to 4 Months
Certain conditions and habits increase the rate at which plaque and tartar accumulate, or they make your gums more vulnerable to inflammation. If any of the following apply, your dentist may recommend a more frequent cleaning schedule:
| Risk Factor | Why It Matters | Suggested Interval |
|---|---|---|
| Active gum disease | Periodontal pockets harbour bacteria that regular brushing cannot reach | Every 3–4 months |
| Diabetes | Elevated blood sugar levels increase susceptibility to infection and slow healing | Every 3–4 months |
| Smoking or tobacco use | Reduces blood flow to the gums, masks early signs of disease, and slows recovery | Every 3–4 months |
| Cardiovascular disease | Oral bacteria may contribute to systemic inflammation | Every 3–6 months |
| Pregnancy | Hormonal changes can cause pregnancy gingivitis and increased gum sensitivity | Every 3–4 months |
| Weakened immune system | Medications or conditions that suppress immunity make infections more likely | Every 3–4 months |
| Heavy tartar buildup | Some individuals naturally produce tartar faster regardless of home care | Every 3–4 months |
If you have been diagnosed with gum disease, periodontal therapy (scaling and root planing) may be recommended as part of your treatment. Following that initial treatment, a maintenance cleaning every three to four months helps keep the condition under control.

What Happens During a Professional Cleaning
A professional dental cleaning — formally called a prophylaxis — is more thorough than anything you can accomplish at home, no matter how diligent your routine. Here is the typical process:
The Professional Cleaning Process
Oral Examination
Your hygienist checks for signs of cavities, gum inflammation, oral cancer, and other concerns.
Scaling
Specialised instruments remove plaque and hardened tartar from above and below the gum line.
Polishing
A gritty paste buffs away surface stains and smooths tooth surfaces to make it harder for plaque to adhere.
Flossing & Rinse
Professional flossing reaches between every tooth, followed by a rinse to clear debris.
Fluoride Treatment
A concentrated fluoride application strengthens enamel and provides additional cavity protection.
During your visit, your dentist or hygienist may also take digital X-rays to check for issues below the surface, such as decay between teeth, bone loss, or impacted teeth. A comprehensive checkup combines the cleaning with a thorough examination of your entire mouth.
The Connection Between Oral Health and Overall Health
Regular dental cleanings are not just about keeping your smile looking good — they play a role in your overall systemic health. Poor oral health has been associated with a range of conditions, including heart disease, stroke, diabetes complications and respiratory infections, though the mechanisms are still being studied.
The mouth is a gateway to the rest of the body. Bacteria from untreated gum disease can enter the bloodstream and contribute to inflammation elsewhere. Keeping your gums healthy through regular cleanings is one of the simplest ways to support your long-term wellbeing.
Worth Noting
Oral cancer screenings are a standard part of dental checkups at Orion Dental. Early detection significantly improves outcomes, and these screenings take just a few minutes during your regular visit.
What You Can Do Between Cleanings
Professional cleanings are essential, but your daily habits have the single greatest impact on your oral health. Here are the fundamentals:
Brush Twice Daily
Use a soft-bristle brush and fluoride toothpaste for at least two minutes each session. Pay extra attention to the gum line.
Floss Every Day
Flossing removes plaque and food particles from between teeth where your brush cannot reach.
Limit Sugary Snacks
Bacteria feed on sugar and produce acid that erodes enamel. Reduce frequency of sugary foods and drinks.
Stay Hydrated
Water helps rinse away food particles and keeps saliva production healthy — your mouth's natural defence.
Avoid Tobacco
Smoking and chewing tobacco dramatically increase your risk of gum disease, tooth loss, and oral cancer.
Replace Your Brush
Swap out your toothbrush (or brush head) every three months, or sooner if the bristles are frayed.
Signs You May Need a Cleaning Sooner Than Scheduled
Don't wait for your next scheduled appointment if you notice any of the following:
Warning Signs
- Gums that bleed when you brush or floss
- Persistent bad breath that does not improve with brushing
- Visible tartar buildup along the gum line
- Gums that appear red, swollen, or tender
- A bad taste in your mouth that lingers throughout the day
- Teeth that feel rough or gritty even after brushing
These symptoms can indicate the beginning stages of gum disease or excessive tartar accumulation. Catching these issues early — before they progress — is far simpler and less costly than treating advanced problems down the road.

Frequently Asked Questions
Common questions about dental cleaning frequency
Is twice a year enough for dental cleanings?
For many people with good oral health and low risk factors, twice-yearly cleanings are sufficient. However, individuals with gum disease, diabetes, or a history of frequent cavities may benefit from cleanings every three to four months.
What happens if I skip my dental cleaning?
Skipping cleanings allows plaque and tartar to build up in areas your toothbrush cannot reach. Over time, this can lead to cavities, gum disease, and even tooth loss. Early-stage issues that would have been caught at a routine visit may progress unnoticed.
Do children need dental cleanings as often as adults?
Yes. Children should typically visit the dentist every six months. Their developing teeth are particularly vulnerable to decay, and regular visits help monitor the eruption of permanent teeth and catch any concerns early.
Can my dentist tell me how often I should come in?
Absolutely. Your dentist will assess your oral health, review your medical history, and consider risk factors like smoking or diabetes to recommend a personalised cleaning schedule tailored to your needs.
Are dental cleanings covered by insurance in Ontario?
Most dental insurance plans in Ontario cover two cleanings per year. If your dentist recommends more frequent visits, check with your provider — many plans offer additional coverage for patients with documented periodontal conditions.
What is the difference between a regular cleaning and a deep cleaning?
A regular cleaning (prophylaxis) removes plaque and tartar from above the gum line. A deep cleaning (scaling and root planing) goes below the gum line to treat periodontal pockets and is typically recommended when gum disease is present.
