Does kissing make your teeth whiter?

This blog post will address the question, “does kissing make your teeth whiter?” and cover topics like is kissing good for your teeth, what research says, benefits of kissing on oral health and ways to get your teeth whiter other than kissing.

Does Kissing Make Your Teeth Whiter?

Yes, kissing makes your teeth whiter. Kissing your partner generates a lot of saliva that washes away any food particles or  plaque deposits on the teeth surface and thus gives your teeth a stain-free and whiter look.

Saliva produced while kissing neutralises the demineralising acids released by cavity-causing bacteria and therefore prevents enamel erosion and dentin exposure, maintaining the natural white shade of your teeth.

Is Kissing Good For Your Teeth?

Kissing is good for your teeth as kissing stimulates the salivary glands, producing saliva, a natural mouth cleanser, in larger quantities. 

Saliva washes away any food particles or food debris, preventing plaque deposition or cleaning away the plaque deposited and hence preventing the formation of cavities and tooth decay.

Kissing also keeps the mouth moist and prevents the food particles from sticking, not allowing any cavity-causing bacteria to attack and produce enamel demineralisation.

Preventing enamel demineralisation keeps the enamel strong and does not allow cavities to form.

What Does Research Say?

The published studies focus mostly on saliva and its benefits on oral health and not much has been studied with respect to kissing and its oral health benefits.

According to a research study published in the journal of American Dental Association, stimulated saliva flow reduces the incidence of dental caries.

An article published in the journal of American Dental Association reports saliva to have a remineralising effect on teeth, making teeth resistant to decay.

Overall, most of the studies have reported and concluded stimulated salivary flow to be effective in prevention of cavity formation and tooth decay.

The stimulated salivary flow is successfully achieved while kissing with passion and love and hence it can be concluded that kissing does play a role in keeping teeth free of cavities, decay and stain and hence make your teeth look whiter and stronger.

Benefits Of Kissing On Oral Health

Kissing may have a significant positive effect on oral health due to its saliva stimulating ability that may result in:

  • Normal pH maintenance – Stimulated saliva with the help of its acid neutralising components such as bicarbonate, phosphate and protein, helps maintain a normal pH of 6-7.5 in the oral cavity. This further prevents any damage to the enamel and keeps the teeth stronger.
  • Prevent enamel demineralisation – Stimulated saliva due to kissing contains a good amount of calcium hydroxyapatite which prevents demineralisation of enamel, resulting in cavity protection and natural whiter shade due to enamel being intact.
  • Enhanced protection from tooth decay and infection – Kissing stimulates salivary gland and enhances stimulated salivary flow. Stimulated saliva so produced contains certain proteins such as lysozyme and lactoferrin that have significant antimicrobial properties, protecting the teeth from any decay or infection.
  • Strong Body Defence/Immunity – There isn’t much research on how kissing may boost the body’s defence but surely it may increase the body’s resistance to certain germs.
