Dental cleanings are one of the simplest and most effective ways to protect your smile — but how often do you actually need one? While most people have heard the classic “twice a year” advice, the ideal frequency can vary depending on your individual oral health.

For those with healthy teeth and gums, visiting the dentist every six months is typically enough. These routine cleanings remove built-up plaque and tartar, help prevent cavities, and allow your dentist to spot any early signs of problems before they become serious. Plus, they’re an opportunity to polish your teeth and leave your smile feeling fresh and bright.

However, not everyone fits into the twice-a-year mold. If you’re someone who’s more prone to plaque buildup, gum disease, or recurring cavities, your dentist might recommend cleanings every three to four months instead. People who smoke, wear braces or aligners, or have conditions like diabetes may also benefit from more frequent visits. These groups are often at higher risk for gum inflammation, bone loss, and other complications that can be managed more effectively with regular professional care.

Even if your teeth look and feel fine, it’s important to remember that not all dental issues cause pain right away. Plaque can quietly accumulate under the gums, harden into tartar, and lead to irritation or infection that’s easy to miss without a trained eye. Waiting until something feels wrong often means the problem has already progressed.

In short, regular dental cleanings are a small commitment that can make a big difference. Whether it’s twice a year or more often, your dentist will help you decide what schedule keeps your smile healthiest. Prevention always costs less — and hurts less — than treatment.
