Dental hygienists are specially trained to work as part of the dental team, to give care to patients.
They play an important part in dental health care and are mainly concerned with preventive dental health and treating gum disease - showing you correct home care and helping to keep your teeth and gums healthy.
The hygienist's main work is to prevent and treat gum disease including professionally cleaning your teeth. This is usually called ‘scaling and polishing'. 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. If it is not brushed away properly, this hardens to form tartar which you cannot remove yourself. They also give advice on diet and preventing dental decay. The hygienist will work alongside your dentist to give you care that is tailored to your needs.
Dental hygienists also take dental x-rays. The dentist will use these to help diagnose problems and decide on the possible treatment. All hygienists that take x-rays will have had proper training and will hold a certificate.
If the dentist suggests that you or your child have fissure sealants or fluoride varnishes, they may refer you to the dental hygienist because these are treatments they are trained to carry out.
Tooth whitening is also often carried out by the dental hygienist under the prescription of your dentist.
Not all practices have a hygienist. However, more of them now offer this as part of the service to patients, using part-time and full-time hygienists. Hygienists see patients directly as well as under the prescription of a dentist. If your practice does not have a hygienist, your dentist can either refer you to another dental practice or a hygienist practice. Or you can approach a practice yourself to ask if you can see the hygienist there.
Regular professional cleaning, combined with looking after your teeth and gums well at home, will help keep your mouth healthy. A clean and healthy mouth will improve your appearance, help you to keep your teeth and give you fresh breath, and help to maintain your general health.
This is what the training of the hygienist is all about. Carefully removing the hard deposits of tartar (or ‘calculus') that build up on the teeth and teaching you how to prevent them coming back, will go a long way towards slowing 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 the rate at which your teeth decay.
Regular visits and advice will help build your confidence in keeping your mouth healthy.
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.
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 information see our ‘Tell me about' - Pit and fissure sealants.
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.
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 discomfort.
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, by getting a written quotation.
Practices should have a price list at their reception giving a guide to the prices they charge for the service.
You can do a great deal to help yourself and the hygienist, as you are in control of your mouth 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 now available including specialist toothpastes, power or electric toothbrushes, and mouthwashes. Your hygienist will recommend those that are best for you.
We recommend you follow three simple steps to help keep your teeth and gums healthy.
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 in turn cancels out the acid produced in your mouth after drinking and eating.
