What is toothpaste?

In the early years, toothpaste was made from hydrogen peroxide and baking soda. With the advancement in dentistry, toothpaste was modified to suit the changing needs of dental patients. Typically, toothpaste is one of the most crucial oral health aids which come in the form of a paste or gel dentifrice. It is generally used with a toothbrush to clean the teeth and maintain good oral hygiene.

History of toothpaste

In the early days, tooth powder was known as the best abrasive for teeth cleaning. It consisted of powdered eggshells, pumice, and myrrh. Later the toothpowders were made from a combination of baking soda and hydrogen peroxide. Pre-mixed toothpaste was created for the first time in the 19th century. However, they were not used as much as the toothpowder.

Newell Sill Jenkins and Willoughby D. Miller developed the first toothpaste containing disinfectant and named it as Kolynos, which means disease prevention. Fluoridated toothpaste came into existence in the early 1890s by a German manufacturer. In 1995, crest launched the first clinically proven fluoridated toothpaste, which became popular because of its anticavity properties. Today, there is a wide range of toothpaste available to take care of every dental need of the people worldwide.

What is the importance of toothpaste?

Poor oral hygiene is one of the primary cause of gum disease. Plaque and bacteria develop to start developing after every meal. Dentifrices like toothpaste provide a base with therapeutic properties to solve the issue of poor dental health.

Toothpaste consists of several ingredients that have anticaries, antimicrobial, and antibacterial properties which ensure natural health of the gums. Moreover, it reduces the risk of tooth decay and cavity formation. The detergents create foam in the mouth which loosens the plaque and bacteria from the tooth surface. (1)

Fluoridated toothpaste is enamel remineralizes and contribute to strengthening the tooth structure. The abrasives help to remove the surface stains, debris, and polish the tooth surface. Additionally, toothpaste is the best mouth fresheners that leave the mouth with a clean feeling.

What are the types of toothpaste?

Typically, toothpaste is broadly divided into six major types given below –

Whitening toothpaste

With the increasing concern of having pearly white teeth, whitening toothpaste is one of the most popular choices of toothpaste among the population. As the name suggests, these toothpaste primarily help to remove the surface stains and improve the color of the teeth. (2)

Whitening toothpaste usually consists of hydrogen peroxide as the primary bleaching agent. The abrasives in the toothpaste remove the stains from the surface of the toothpaste. One of the conventional abrasive used in whitening toothpaste is sodium tripolyphosphate, which helps to breakdown and dissolve the stains.

Following this, the bleaching agent acts with the enamel layer to improve the shade of the teeth. It is essential to note here that whitening toothpaste does not alter the color of the teeth or reverse a discoloration. It only removes the superficial stains and intensifies the natural tooth color.

It typically takes two to four weeks to get the desired results of whiter teeth. An alternative of whitening toothpaste is a tooth whitening gel. Usually, these toothpaste are safe to use regularly. However, excessive use of whitening toothpaste may damage the tooth.

Anticavity toothpaste or fluoride toothpaste

Fluoride is a natural mineral which is popularly known for its preventive properties. For the past 50 years, fluoride toothpaste has proven to be the best among all other types of toothpaste in bringing a dramatic drop in tooth decay and cavity formation.

Fluoride eliminates the production of bacterial acids that damage the tooth enamel and cause tooth decay. Moreover, fluoride chemically acts with calcium hydroxyapatite crystals of enamel to allow remineralization. This way, it strengthens the tooth and repairs the damage caused by an acid attack in the mouth. (3)

Water fluoridation has been an active contributor in preventing the rate of dental caries and cavity formation in metropolitan cities. However, fluoridated toothpaste add a beneficial topical effect that reacts faster than the fluoride present in water supplies.

Anti-calculus toothpaste

Anti-calculus toothpaste, also known as tartar control toothpaste is another significant type that helps to control plaque and calculus formation in the mouth. Plaque is a sticky biofilm which consists of food debris and bacteria. Most commonly, plaque sticks to the surface of the tooth and around the gums.

Poor oral health care often calcifies the plaque and forms hard calculus or tartar that potentially causes tooth decay and gum disease. Anti-calculus toothpaste contains several ingredients like pyrophosphate, zinc citrate, and triclosan, which provide a useful antibiotic property that kills the disease-causing bacteria in the mouth. (4) Moreover, these toothpaste also help to remove the plaque from the tooth surface and around the gum line.

Smoker’s toothpaste

Smoking often leads to tar deposits on the tooth surface, which stains the teeth and makes it look less appealing. With continuous use of tobacco, the teeth become tainted with yellowish-brown patches. Smoker’s toothpaste contains stronger abrasives and cleaning agents, which specifically help to remove the tough stains from the tooth surface.

However, the results of smoker’s toothpaste are better with habit control. Prolonged and vigorous use of such strong abrasives can cause enamel erosion in the long run.

Desensitizing toothpaste

Tooth sensitivity is a prevalent dental issue suffered by people with a thin layer of enamel, gum recession, and tooth decay. During this time, the teeth of the people become incredibly irritated by cold or hot temperatures, food, or drinks.  Hypersensitivity of teeth is usually caused by exposure of the dentinal layer.

Desensitizing toothpaste is formulated to mask the effects of tooth sensitivity. This toothpaste consists of potassium nitrate and strontium chloride, which block the dentinal tubules to reduce the perception of sensitivity. Typically, it takes around two to four weeks for the teeth to desensitize completely.

Herbal toothpaste

For people who prefer to use oral health care products made from natural earth elements, herbal toothpaste is the best product. These toothpastes are fluoride-free and do not contain sodium lauryl sulfate. (5) Herbal toothpaste includes a wide variety of plant extracts and natural minerals. Some of the common ingredients of herbal toothpaste include –

  • Natural baking soda
  • Aloe vera
  • Eucalyptus oil
  • Myrrh
  • Strawberry plant extracts
  • Essential oils

  • Breath freshener – the primary purpose for such toothpaste is to treat halitosis and provide a long-lasting freshness in the mouth. These toothpaste contain a higher concentration of flavoring agents.
  • Children’s toothpaste – usually, kid’s toothpaste contain less fluoride or no fluoride depending on the age of the child. Typically, children under three years of age are not recommended to use fluoridated toothpaste as it increases health risks upon swallowing.

Moreover, children do not require the same intensity of cleaning with toothpaste abrasives as compared to an adult. Children are often picky about their toothpaste selection and look at things like texture, taste, and consistency of the toothpaste. Therefore, children’s toothpaste comes under a separate category.

Some of the common abrasive agents include – aluminum hydroxide, calcium carbonate, calcium hydrogen phosphates, silica, and zeolites. Although they are well known for their cleaning action, the abrasive particles can cause minor enamel erosion. Mica is a gentle abrasive agent who has a mild activity as compared to other toothpaste abrasives.

Detergent

Detergents like sodium lauryl sulfate are used to create the foaming effect of the toothpaste. They add an extra cleansing mechanism to allow thorough cleaning of the teeth and gums.

Humectants

Humectants usually trap water in the toothpaste and allow proper binding of all the ingredients. This gives the toothpaste a particular gel-like consistency. Sorbitol, glycol, and glycerol are commonly used humectants. (7)

Fluoride

Fluoride is a well-known cavity fighter and an active ingredient in toothpaste that is specially formulated for preventing dental caries. Additionally, fluoride also helps in remineralization of the enamel and strengthens the tooth structure.
