What are Tongue Cleaners?

Learn what it is all about below
Tongue Cleaners and halitosis (Bad breath)
The surface of the tongue provides a unique and favourable home for bacteria, it has a large surface area which helps to provide binding ability of bacteria, food debris, and saliva. This allows an ideal growing spot for bacteria. Certain bacteria can also produce volatile by products that can contribute to halitosis (bad breath). As a result, it is estimated that approximately 85% of all halitosis cases have their origin in the mouth and of these 50% are related to the tongue. Therefore, many clinicians have recommended that patients use tongue cleaning products be that by a toothbrush or scraper/cleaner to clean the bacterial build up, food debris and dead cells from the surface of the tongue especially if you are the 50% of adults that suffer from bad breath.

    Tongue Cleaners can be specially designed tongue cleaners/scrapers, the bristles on everyday toothbrushes or even specialised rubber/bristles on the back of some toothbrushes. They are useful at removing bacterial biofilm (build up) on the back of your tongue.

  • It is advised that you hold your tongue out while cleaning this helps you reach right at the back of the tongue. Then move from the back towards the front tip of the tongue. Repeat a couple of times until there is little grime that comes off the tongue. Rinse the scraper thoroughly during and after cleaning.
  • Be careful that you do not scrape your tongue too hard. As this can cause trauma and hurt the taste buds on the tongue.
  • In general, I like to advise using a tongue cleaner or brush in addition to your toothbrushing in the morning then focus on flossing and brushing your teeth in the evening. This is only to simplify things and ensure continual use. As repetition and consistent action is one of the most important factors for good hygiene.
    Halitosis

    Halitosis is bad breath related to foul smells coming from the mouth. It is important to understand that not all bad breath is of mouth origin. It can also be related to your nose, gut, or medication. Therefore, it is important you see your oral health professional in order to help determine its origin before seeking other treatment. If it is related to the mouth it is usually caused by volatile sulfur compounds (VSC) that arise from bacterial breakdown of proteins. Other causes can include certain foods (like coffee and garlic), smoking, gum disease, dry mouth, tonsilitis and poor oral hygiene.


    Treatment of halitosis

    Currently the best way to treat halitosis is to limit smelly causes (smoking,certain foods), gently remove bacteria and nutrients from the tongue via a tongue cleaner or toothbrush and finally have regular check ups from a oral health practitioner as it may be gum related requiring a professional clean.

  • Morning breath is very normal and is caused by a reduced saliva production at night-time. This problem will resolve as soon as you provide adequate oral hygiene.
  • Mint tablets, sprays or chewing gum can help with short term masking the bad breath.
  • Mouth rinses that contain chlorhexidine or essential oils have been found to be only effective for short term. Lasting only 304 hours. Correct oral hygiene (flossing, tooth brushing and tongue cleaning) is more effective.
    Tongue Cleaners Vs ToothBrushes

    Cochrane studies have found that tongue scrapers or cleaners are slightly more effective than toothbrushes as a means of controlling halitosis in adults. This study showed that although tongue cleaners are generally well accepted, the effects of tongue cleaning is short lived and there is some limited evidence that tongue trauma can occur with prolonged use. What does this mean? basically if you a prone to oral induced halitosis, then you may benefit from tongue cleaners. But remember to have regular check ups with the dentist in order to see how your cleaning is going and if there is any trauma happening to the tongue. As well as being able to address the other causes of halitosis.
