Key facts

• Routine clean usually takes about 30–60 minutes
• Heavy tartar may need two or more sessions
• Interval is reviewed at each check-up

The usual six-month interval and why it varies

Six months is a common starting point because plaque that is missed during brushing hardens into tartar within days to weeks, and tartar cannot be removed with a toothbrush. A professional clean every six months removes this build-up before it causes significant gum inflammation. However, people differ. Some form tartar slowly and keep healthy gums with an annual clean, while others build it up quickly behind the lower front teeth and need more frequent visits. The right interval is the one that keeps your gums healthy between visits, and Dr. Fariba Alnoory reviews it at each check-up.

Who needs cleaning more often

A shorter interval of three to four months is often recommended for people with a history of gum disease or bone loss, those who smoke or use shisha, people with diabetes, pregnant women with gum inflammation, patients wearing fixed braces or aligners, those with dry mouth from medication, and people with implants, bridges or crowded teeth that are hard to clean. After deep cleaning for gum disease, regular maintenance visits are especially important, because pockets can refill with bacteria if not monitored. Your dentist will explain why a particular interval is advised and how improved home care might allow it to be extended.

How long a cleaning session takes

A routine scale and polish for a mouth with healthy gums and light tartar usually takes around 30 to 45 minutes, including a check of the gums. If there is moderate tartar or staining from tea, coffee or smoking, it may take closer to an hour. A full first visit that includes an examination and X-rays will take longer. Deep cleaning for gum disease is usually divided into longer appointments, often treating one or two sections of the mouth at a time under local anaesthetic. The team at Manhal can tell you the expected time when you book.

How many sessions heavy tartar needs

If tartar has built up over years, especially below the gum line, it may not be realistic or comfortable to remove it all in one visit. Dr. Fariba Alnoory first assesses the gums and may divide treatment into two or more sessions, allowing the gums to settle in between. Very heavy deposits above the gum are often removed first, followed by a review after a few weeks when inflammation has reduced and deeper areas can be cleaned more precisely. In gum disease, a re-evaluation visit checks pocket depths and decides on the maintenance interval. The number of sessions is set out in your written plan.

Keeping the interval effective at home

Professional cleaning works only alongside good daily care. Brush twice a day for two minutes with a fluoride toothpaste, clean between your teeth daily with floss or interdental brushes, and limit sugary snacks and drinks between meals. An electric toothbrush can help some people remove more plaque. If your gums bleed when brushing, do not stop; it is usually a sign of inflammation that improves with gentle, thorough cleaning. Book an earlier visit if you notice persistent bleeding, bad breath, receding gums, loose teeth or gum swelling, rather than waiting for your next routine appointment.

Professional cleaning removes hardened tartar that brushing can't, polishes away surface stains, and lets the dentist spot gum disease early.
