 Mouthwash/ Mouth rinse/ Mouth bath.

Mouthwash, mouth rinse, oral rinse, or mouth bath  is a liquid which is held in the mouth passively or swilled around the mouth by contraction of the perioral muscles and/or movement of the head, and may be gargled, where the head is tilted back and the liquid bubbled at the back of the mouth.

Although confusingly similar, they are actually two very different products which serve two very different purposes.

A mouth rinse is normally used prior to brushing and flossing your teeth. The purpose of a mouth rinse is to freshen your breath and to help prevent a buildup of plaque on the surfaces of your teeth.

Mouth rinses often contain alcohol, for its antibacterial effect and fluoride or other agents to help protect your teeth.

A mouthwash, on the other hand, is used after brushing and flossing your teeth.

Mouthwashes are basically antiseptic solutions that are used to kill or retard the growth of bacteria in your mouth after brushing. To do this, mouthwashes commonly contain a high percentage of alcohol up to 27 percent and antiseptics. Other common ingredients include essential oils, flavoring agents, hydrogen peroxide, zinc, and fluoride.

For good dental health, mouth rinse and mouthwash are good additions to your daily dental care regimen.

Antimicrobial mouth rinses are much more powerful than over-the-counter mouthwashes, reducing certain bacteria that cause gum disease to an almost undetectable level. The most commonly prescribed is Chlorhexidine, and your dentist can recommend how to use it as part of your treatment regimen.

Your everyday over-the-counter mouthwashes are the mildest form of antimicrobials, meaning that they can reduce the number of microbes or bacteria in the mouth. Certain bacteria are contributing factors for both tooth decay and gum disease. Chlorhexidine is the most often prescribed oral mouth rinse, used to reduce the number of bacteria in the mouth. Used as directed by your dentist, Chlorhexidine can reduce certain gum disease-causing bacteria to an almost undetectable level. And in some cases your dentist may also prescribe an oral antibiotic or locally applied chemotherapeutic to help further reduce other bacteria causing your gum disease. Studies have shown that combinations of antibiotics, chemotherapeutics, and Chlorhexidine can reduce the need for periodontal surgery by upwards of 80%.

Usually mouthwashes are antiseptic solutions intended to reduce the microbial load in the oral cavity, although other mouthwashes might be given for other reasons such as for their analgesic, anti-inflammatory or anti-fungal action. Additionally, some rinses act as saliva substitutes to neutralize acid and keep the mouth moist in xerostomia (dry mouth).  Cosmetic mouthrinses temporarily control or reduce bad breath and leave the mouth with a pleasant taste.

Rinsing with water or mouthwash after brushing with a fluoride toothpaste can reduce the availability of salivary fluoride. This can lower the anti-cavity re-mineralization and antibacterial effects of fluoride.  Fluoridated mouthwash may mitigate this effect or in high concentrations increase available fluoride.  A group of experts discussing post brushing rinsing in 2012 found that although there was clear guidance given in many public health advice publications to "spit, avoid rinsing with water/excessive rinsing with water" they believed there was a limited evidence base for best practice.

The health benefits of salt have been recorded in some of the oldest medical scripts. It was believed that salt could dry out and disinfect wounds. Ancient Egyptian medicine prescribed anti-infective solutions, which had salt as a base ingredient. These were administered orally, applied as an ointment or suppository. Greek medicine also made us of salt by mixing it with honey to create a topical application to disinfect cuts and wounds.

Salt is a mineral composed primarily of sodium chloride (NaCl). Rinsing the mouth with a NaCl solution is an old remedy believed to promote healthy gums and encourage recovery from mouth ulcers.

Although there are benefits to using a salt water mouth rinse, it shouldn't replace your daily oral hygiene routine. Taking good care of your teeth starts with brushing twice a day and interdental cleaning. Doing this effectively removes plaque, bacteria, and food particles that can get stuck between the teeth. Before you use this at-home remedy, consult with your dentist to learn about how and when to use it.

Mouthwash is not recommended for children younger than 6 years of age.  Swallowing reflexes may not be well developed in children this young, and they may swallow large amounts of the mouthwash, which can trigger adverse events like nausea, vomiting, and intoxication (due to the alcohol content in some rinses).

Ingredients:

Alcohol is added to mouthwash not to destroy bacteria but to act as a carrier agent for essential active ingredients such as menthol, eucalyptol and thymol which help to penetrate plaque.

Benzydamine/Difflam (analgesics); In painful oral conditions such as aphthous stomatitis, analgesic mouthrinses (e.g. benzydamine mouthwash, or "Difflam") are sometimes used to ease pain, commonly used before meals to reduce discomfort while eating.

Benzoic acid, acts as a buffer.

Betamethasone is sometimes used as an anti-inflammatory, corticosteroid mouthwash. It may be used for severe inflammatory conditions of the oral mucosa such as the severe forms of aphthous stomatitis.

Cetylpyridinium chloride (antiseptic, antimalodor) containing mouthwash (e.g. 0.05%) is used in some specialized mouthwashes for halitosis. Cetylpyridinium chloride mouthwash has less anti-plaque effect than chlorhexidine and may cause staining of teeth, or sometimes an oral burning sensation or ulceration.

Chlorhexidine digluconate and Hexetidine is a chemical antiseptic and is used in a 0.12–0.2% solution as a mouthwash. However, there is no evidence to support that higher concentrations are more effective in controlling dental plaque and gingivitis. It has anti-plaque action, but also some anti-fungal action. It is especially effective against Gram-negative rods.

Fluoride (anticavity), Anti-cavity mouth rinses use sodium fluoride to protect against tooth decay. Fluoride-containing mouth rinses are used as prevention for dental caries for individuals who are considered at higher risk for decay, due to xerostomia related to salivary dysfunction, or side effects of medication, those who do not drink fluoridated water, those who are physically unable to care for their oral needs (brushing and flossing), and treatment for those with dentinal hypersensitivity, gingival recession/ root exposure.

Flavoring agents and Xylitol, Flavoring agents include sweeteners such as sorbitol, sucralose, sodium saccharin, and xylitol, which stimulate salivary function due to their sweetness and taste and helps restore the mouth to a neutral level of acidity. Xylitol rinses double as a bacterial inhibitor and have been used as substitute for Alcohol to avoid dryness of mouth associated with Alcohol.

Hydrogen peroxide can be used as an oxidizing mouthwash (e.g. Peroxyl, 1.5%). It kills anaerobic bacteria, and also has a mechanical cleansing action when it froths as it comes into contact with debris in mouth. It is often used in the short term to treat acute necrotising ulcerative gingivitis. Side effects with prolonged use might occur, including hypertrophy of the lingual papillae.
