Full Mouth Disinfection


Full Mouth Disinfection is a non-invasive maintenance course undergone to treat advanced or chronic cases on periodontitis. It is the only procedure available to treat this level of gum disease, and it can lead to serious complications if not undergone when advised.


Chronic periodontitis is an advanced form of gingivitis that hasn’t been resolved quickly enough. Keeping your teeth clean with the recommended twice-daily brushing, and a regular visit to your dental hygienist is a sure way of avoiding diseases of this nature. By doing this, you are preventing the development of plaque build-up in and around the teeth and gum pocket areas. Not cleaning plaque correctly will inevitably lead to the development of hard calculus, and will encourage the onset of gingivitis.

Some of the worst cases of chronic periodontitis have led to the jaw bone becoming destroyed and even tooth loss. This is treatable with a full mouth disinfection when you spot early symptoms, such as excessive gum bleeding and inflammation of the gums, which are quite obvious to spot. If you believe you are showing signs of early periodontitis, you should present this to your dentist for a full consultation.

The procedure of a full mouth disinfection is aimed at healing gums and is the most effective of its kind. It is important to note that the procedure is non-invasive, meaning it will not cause you any pain. The whole process is done under local anaesthetic to the afflicted area, and it typically takes up to two sessions (depending on the extent of damage).

In order to remove soft plaque and hard calculus from the teeth, the dentist will use a combination of scaling and root planning completed with the appropriate dental instruments. The gums are then thoroughly disinfected with a chlorhexidine mouthwash, which prevents further inflection and healing gums. The mouth rinse acts as an antiseptic to achieve this. This mouth rinse will be given to you to use at home as part of the overall treatment. This should be used twice daily for approximately 30 seconds each time, and should be done for a month after the in-practice treatment.
