How plaque differs from tartar
Soft plaque forms every day from food residue and bacteria — it can be removed with a brush and floss. But if it isn't cleared in time, it mineralizes with the salts in saliva and hardens into tartar, which a brush can no longer remove — only a dentist, with specialized instruments.
Why this is about more than looks
Tartar most often builds up right at the gumline and between teeth — exactly where gum inflammation starts. Left untreated, that inflammation can progress into periodontitis, one of the leading causes of loosening and losing teeth in adults, and the process is often symptom-free in its early stages.
What the dentist actually does during a hygiene session
An ultrasonic scaler removes hardened tartar above and below the gumline without damaging the enamel, after which the tooth surface is polished — this not only removes staining from coffee and tea but also makes the enamel smoother, so new plaque builds up more slowly.
How often you actually need it
The standard recommendation is once every 6 months, timed with your preventive check-up. But if you're prone to fast tartar buildup, wear braces or implants, or smoke, your dentist may recommend more frequent visits — every 3–4 months.
Hygiene before other procedures
Professional hygiene is often done not just for prevention but as a mandatory first step before whitening, veneers, or braces — a clean tooth surface is needed so the outcome of the treatment that follows is predictable.
