The standard advice for how often a dental cleaning should be done is every six months, but this doesn’t tell the whole story. Some people may need a visit every three months, while others might be fine once a year.
Your oral health is unique, so your care plan should be too. We’ll break down how a hygienist decides on the right schedule for your specific needs.
The “Every Six Months” Rule: A Great Starting Point for Most
The “every six months” rule is a great guideline for most people with healthy smiles. Here’s a quick look at why this schedule works so well.

When You Might Need Cleanings More Often (Every 3-4 Months)
For some people, waiting six months is just too long. This isn’t a bad thing at all! It just means your smile needs a little extra care to stay healthy. Here are a few reasons why we might suggest you come in more often.
- If You Have Gum Disease: If you have sore or bleeding gums (gingivitis), more frequent cleanings help to manage the condition and restore gum health. It’s a very important step to keep your gums healthy.
- If You’re a Smoker: Using tobacco can cause tartar to build up much faster. Coming in more often helps us stay on top of it.
- Certain Health Conditions: Some health issues, like diabetes, can affect your oral health. Our goal is to provide excellent cavity prevention, and that means looking at your overall health.
- During Pregnancy: When you’re pregnant, hormonal changes can make your gums extra sensitive. More frequent cleanings can keep them comfortable and healthy.
Is It Ever Okay to Go Less Often?
You might also be wondering if you can go longer than six months. For a very small number of people who have an extremely low risk of cavities or gum disease, once a year might be okay.
However, this is very rare. This is a decision that should only be made after a dental professional has completed a thorough check-up of your mouth. For most of us, waiting a full year is too long.
