How long does a dental cleaning take? Most routine check-up and clean appointments take about 30 to 60 minutes. The exact time depends on how long it has been since your last visit, how much tartar has built up and whether X-rays are needed. This guide explains what happens during the appointment and how soon you can eat afterwards.

What affects how long a dental clean takes?
- Time since your last clean. More tartar takes longer to remove.
- Whether it is your first visit. A first appointment includes your dental and medical history, so allow extra time.
- X-rays. These add a few minutes when they are needed.
- Gum health. If you have gum disease, cleaning below the gum line takes longer and may be spread over more than one visit.
- Anything else found. If we find something that needs explaining, we take the time to go through it with you.
What happens at a check-up and clean?
- History. We ask about your general health, medicines and any problems you have noticed.
- Examination. We check your teeth, gums, existing fillings and the soft tissues of your mouth.
- X-rays, if needed. These show decay between the teeth and the bone around the roots.
- Scale. Tartar and plaque are removed with an ultrasonic scaler and hand instruments.
- Polish. The teeth are polished to remove surface stain and leave them smooth.
- Fluoride and advice. A fluoride treatment may be applied, and we go over brushing and cleaning between your teeth.

How long after a teeth cleaning can I eat?
After a routine clean you can usually eat and drink straight away. There are two exceptions:
- Fluoride treatment. If fluoride was applied, you will usually be asked to wait about 30 minutes before eating or drinking so it has time to work. We will tell you what applies to the product used.
- Local anaesthetic. If part of your mouth was numbed, wait until the numbness wears off before eating so you do not bite your lip, cheek or tongue.
Your teeth can feel sensitive for a day or two after a clean. Avoiding very hot or very cold food and drink for the rest of the day helps.
How long does a deep clean take?
A deep clean treats gum disease by removing tartar from below the gum line. It takes longer than a routine clean, is often done with local anaesthetic, and is commonly split over two or more appointments so one part of the mouth is treated at a time. See gum disease treatment.
How often should I have a check-up and clean?
For most people, every six to twelve months. Your dental practitioner may suggest more frequent visits if you build up tartar quickly, have gum disease or are at higher risk of decay. Read how often should you visit the dentist? for more detail.
Dental clean FAQs
Does a scale and clean hurt?
Most people find it comfortable. Areas with a lot of tartar or inflamed gums can be tender. Tell us if anything is sore and we can adjust or numb the area.
Can I go back to work after a dental clean?
Yes. There is no recovery time after a routine check-up and clean.
Why do my teeth feel different after a clean?
The surfaces are smoother, and you may notice small spaces near the gum line that were previously filled with tartar. This is normal.
How long does a child’s check-up take?
Children’s check-ups are often shorter than adult visits, particularly for younger children. See our kids dentist page.
