16914 Oral Hygiene

Overview

Oral hygiene means keeping your mouth clean and healthy. It includes brushing your teeth, cleaning between them, eating and drinking wisely, and seeing a dental professional for check-ups. Good oral hygiene helps prevent tooth decay (holes in teeth), gum disease (swelling and infection of the gums), and tooth loss.

Yes. Nearly everyone needs to care for their teeth and gums every day. Tooth decay and gum disease are among the most common health problems worldwide.

People of all ages. It matters especially for children learning to brush, older adults, people with dry mouth, diabetes, or disabilities, and anyone who smokes or has limited access to dental care.

Symptoms

Common symptoms

• A sticky, pale film on the teeth, called plaque
• Hard yellow or brown build-up near the gums, called tartar or calculus
• Bleeding gums when brushing or cleaning between teeth
• Bad breath that does not go away
• Tooth sensitivity to hot, cold, or sweet foods
• Toothache or pain when chewing
• Red, puffy, or tender gums
• Gums that pull away from the teeth, making teeth look longer

Symptoms in children

• Not wanting to brush or needing help to brush well
• White or brown spots on the teeth, which can be an early sign of decay
• Bleeding gums or bad breath
• Pain when eating or drinking something cold or sweet
• Teeth that look worn, chipped, or discoloured

Symptoms in older adults

• Dry mouth, which can raise the risk of decay and gum problems
• Root decay, where the softer part of the tooth root is exposed
• Gum recession and sensitive teeth
• Denture sores or problems cleaning dentures
• Difficulty holding a toothbrush because of arthritis or weakness
• Loose teeth or changes in how dentures fit

Causes

Main causes

• Plaque: bacteria in the mouth mix with sugars from food and drinks to form a sticky film on teeth.
• Not brushing or cleaning between teeth often enough, so plaque builds up.
• Sugary foods and drinks, especially between meals, feed the bacteria that cause decay.
• Smoking and tobacco use, which raise the risk of gum disease.
• Dry mouth from medicines, health conditions, or ageing, which lets plaque build up faster.
• Not having regular dental check-ups, so early problems are missed.

Risk factors

• A diet high in sugar or frequent sugary snacks and drinks
• Smoking or using other tobacco products
• Diabetes or other long-term health conditions
• Dry mouth, including from some medicines
• Pregnancy, when gums can become more sensitive
• Braces, dentures, or other dental work that makes cleaning harder
• Limited access to dental care or difficulty affording it
• Dementia, disability, or mental health problems that make daily care harder
• A family history of tooth decay or gum disease

When to see a doctor

See a doctor urgently if:

• You have facial swelling, fever, or pus in your mouth
• You have severe toothache or pain that is getting worse
• A tooth is knocked out, very loose, or badly broken
• Bleeding from your mouth will not stop
• You have trouble swallowing, opening your mouth, or breathing

Book a routine appointment if:

• Your gums bleed often when you brush or clean between your teeth
• You have bad breath that does not improve with daily cleaning
• Your teeth are sensitive or you see spots, holes, or dark areas
• Your gums are red, puffy, or pulling away from your teeth
• You have dry mouth or notice more plaque than usual
• It is time for a regular dental check-up

Diagnosis

A dentist or dental hygienist will look at your teeth and gums, ask about your diet and cleaning habits, and check for plaque, tartar, decay, and gum problems. A general doctor may also check your mouth and refer you to a dental team if needed.

Tests that may be done

• A visual check of your teeth, gums, tongue, and mouth
• A small probe used gently to measure spaces around the teeth, called gum pockets
• Dental X-rays to look for decay between teeth or under fillings
• Questions about pain, bleeding, dry mouth, diet, and medicines

What to expect at your appointment

The check is usually quick and gentle. If you feel anxious, tell the dental team — they can explain each step and agree on a sign for you to raise if you need a pause. You do not need to feel embarrassed; the team is there to help.

Treatment

Treatment depends on what is found. Most people need daily cleaning at home plus regular professional care. If there is decay or gum disease, the dental team can treat it and help you build a cleaning routine that works for you.

Self-care at home

• Brush your teeth twice a day for about two minutes with fluoride toothpaste.
• Clean between your teeth once a day with floss or interdental brushes — your dental team can show you how.
• Spit out toothpaste after brushing rather than rinsing with lots of water, as this keeps fluoride on your teeth.
• Limit sugary foods and drinks, and choose water between meals.
• Do not smoke or use tobacco, and keep alcohol within low-risk levels.
• Replace your toothbrush or brush head every three months, or sooner if the bristles are frayed.
• Visit your dentist as often as they advise for your needs.

Medical treatments

Dental professionals can remove hardened tartar with a gentle deep clean, apply fluoride varnish to strengthen teeth, and fill holes caused by decay. For gum disease, they may offer a more thorough cleaning and a plan to help you clean more effectively. If an infection is present, a dentist may prescribe medicine — follow their instructions and never use leftover medicines. A doctor or pharmacist can advise on pain relief that is safe for you.

When is surgery considered?

Surgery is only needed for some problems. Examples include removing a tooth that is too damaged to repair, treating a severe gum problem, or draining an abscess (a pocket of infection). Your dental team will explain the benefits and risks before any procedure.

Living with this condition

Make oral care part of your normal day, like washing your hands. Keep your brush and interdental cleaners where you can see them, set a timer or use a phone reminder, and pair brushing with another habit such as after breakfast or before bed. If your hands are stiff or weak, try a toothbrush with a larger handle, an electric brush, or a special grip.

Lifestyle tips

• Choose water and plain milk instead of sugary drinks.
• Limit sweets and sugary snacks to mealtimes rather than eating them all day.
• Stop smoking — quitting is one of the best things you can do for your gums.
• Wear a mouthguard for sports that could injure your mouth.
• If you have dry mouth, sip water often and ask a pharmacist or dentist about ways to ease it.
• Keep up regular dental visits, even when your mouth feels fine.

Diet and exercise

A balanced diet with plenty of vegetables, fruit, and fibre supports your general health and your mouth. Regular physical activity helps manage conditions like diabetes that affect gum health. You do not need a special diet — small, steady changes are easier to keep.

Mental health and emotional wellbeing

Tooth pain, bad breath, or missing teeth can affect confidence, sleep, eating, and social life. Fear of the dentist is common and can be managed with a gentle, planned approach. If worry or low mood is overwhelming, speak to your doctor or local mental health service. If you ever feel in crisis, contact your local crisis service or emergency number right away.

Prevention

Yes, most tooth decay and gum disease can be prevented or kept under control. Daily brushing and cleaning between teeth, a lower-sugar diet, not smoking, and regular dental care make the biggest difference.

Vaccines

There is no vaccine that prevents tooth decay or gum disease. Ask your healthcare provider about any vaccines that are right for you.

Screening programmes

Regular dental check-ups are the main way to screen for early problems. Your dentist will tell you how often you need them based on your mouth, health, and risk factors — often every 6 to 12 months, but some people need more or less frequent visits.

Complications

If left untreated

• Tooth decay that can reach the inner part of the tooth and cause pain or infection
• Gum disease that damages the bone holding teeth, leading to loose teeth and tooth loss
• A dental abscess (a pocket of infection) that can spread and make you very unwell
• Bad breath, difficulty eating, and changes in speech or confidence
• Higher risk of problems for people with diabetes or other long-term conditions

Long-term outlook

The outlook is good for most people. Small daily habits and regular dental care can prevent many problems or catch them early. If you already have decay or gum disease, treatment and a plan you can keep up with often make a real difference.
