What is the dental hygienist’s role in the practice?
Dental hygienists are mainly concerned with ‘preventive’ dental health and treating gum disease – showing you correct home care and helping you to keep your teeth and gums healthy. This includes professionally cleaning your teeth by removing plaque and tartar (usually called a ‘scale and polish’ or a prophylaxis). However, perhaps their most important role is showing you the best way to keep your teeth free of plaque. Plaque is a sticky coating that forms constantly on your teeth. Hygienists also give advice about diet and about preventing tooth decay. The hygienist will work with your dental team to give you the care that is tailored to your needs.
What is the dental therapist’s role in the practice?
As well as doing all the work that a dental hygienist does, a dental therapist can also carry out some dental procedures that patients are more used to a dentist doing. A dental therapist can do fillings, extract ‘baby’ teeth, place preformed crowns on baby teeth and do treatments using all the materials a dentist would use. As long as an adult tooth does not need treatment to the nerve of the tooth, a dental therapist can fill or restore any part of the tooth that needs treatment. They do not do restorations, such as crowns, to adult teeth.
Can a dental hygienist do anything else?
Dental hygienists also take dental x-rays. The dentist will use these to help diagnose problems and decide on the possible treatment. Dental hygienists can also place fissure sealants, apply fluoride varnishes and administer fluoride treatments. Other procedures may be carried out by dental hygienists depending on the laws that apply where they work.
Tooth whitening is also often carried out by the dental hygienist, under a prescription from your dentist.
Does every practice have a hygienist?
Not all practices have a hygienist or therapist. However, more of them now offer this as part of the service to patients. They can see patients under the prescription of a dentist, see them as part of a separate treatment plan or can see them independently as part of their own practice. If your practice does not have a hygienist or therapist, your dentist may refer you to one or you can contact them directly.
Can a hygienist help prevent dental disease?
This is what the training of the hygienist is all about. They will carefully remove the hard deposits of tartar (or ‘calculus’) that build up on the teeth and teach you how to prevent them coming back. This will do a lot to slow the progress of gum disease.
By talking to you about your diet, and recommending other preventive measures, the hygienist can help you keep to a routine that will slow down tooth decay. Regular visits and advice will help build your confidence in keeping your mouth healthy.
What other help can be given to adults?
Adults who have a lot of decay can benefit from having fluoride applied. They can also have anti-bacterial gels and solutions applied under the gum to kill the bacteria causing gum disease.
Another very important part of the hygienist’s work is showing you and telling you how to look after your mouth at home. The hygienist may also suggest giving up smoking, as this will reduce staining and improve your general health.
Research has also shown that smokers have more gum disease and lose more teeth than non-smokers. Your hygienist will be able to advise you on various ways of giving up smoking. They can also give you special advice for home care if you have dental implants or orthodontic appliances.
What help is available for children?
Children can benefit from having their teeth polished. The hygienist can also apply fluoride varnishes to help prevent decay.
The permanent (or ‘adult’) back teeth can also benefit from having the biting surfaces sealed. This is done by applying a special plastic coating to the biting surface soon after the teeth come through. For more advice, visit our information on ‘pit and fissure sealants‘.
Why doesn’t the dentist do this work?
Some dentists will do this type of work themselves. However, many now realise that the hygienist has been specially trained to carry out scaling and polishing and can spend longer with you. They are also expert at teaching you how to look after your teeth and gums. Often the hygienist will spend a number of appointments getting the gums healthy ready for the dentist to restore the teeth with crowns and fillings.
Will the treatment hurt?
Scaling and polishing is usually pain free. However, if you do have any discomfort the hygienist can use anaesthetic creams, or give you some local anaesthetic. It is important that you let the hygienist know at the time so they can help with your pain.
Is the treatment expensive?
Costs of treatment with a dental hygienist will vary depending on what is being done, and from practice to practice. It is important to find out the cost before you start.
What does the dental hygienist do in the practice?
You can do a lot to help yourself and the hygienist, as you are the one who looks after your mouth in between visits to the practice. Your hygienist will have shown you how to remove plaque with a toothbrush and fluoride toothpaste.
They will also have shown you how to clean between your teeth with ‘interdental’ brushes, floss or tape.
There are many oral care products you can get, including specialist toothpastes, electric or ‘power’ toothbrushes, and mouthwashes. Your hygienist will recommend those that are best for you.
We recommend that you follow three simple steps to help keep your teeth and gums healthy:
- Brush your teeth last thing at night and at least one other time during the day, with a fluoride toothpaste.
- Cut down on how often you have sugary foods and drinks.
- Visit your dental team regularly, as often as they recommend.
Cutting down the amount of sugar in your diet, and the number of times that you eat during the day, can help to reduce decay. Your hygienist can help you by looking at your decay problem and your diet, and by making some recommendations for you to consider.
Chewing sugar-free gum for 10 minutes after meals can also help to prevent tooth decay. Chewing gum makes your mouth produce more saliva, which cancels out the acid produced in your mouth after drinking and eating.
