Short Essay On Toothbrush And Toothpaste



The toothbrush as we know it today was not invented until 1938. However, early forms of the toothbrush have been in existence since 3000 BC. Ancient civilizations used a "chew stick," which was a thin twig with a frayed end. These 'chew sticks' were rubbed against the teeth.

The bristle toothbrush, similar to the type used today, was not invented until 1498 in China. The bristles were actually the stiff, coarse hairs taken from the back of a hog's neck and attached to handles made of bone or bamboo.

Boar bristles were used until 1938, when nylon bristles were introduced by Dupont de Nemours. The first nylon toothbrush was called Doctor West's Miracle Toothbrush. Later, Americans were influenced by the disciplined hygiene habits of soldiers from World War II. They became increasingly concerned with the practice of good oral hygiene and quickly adopted the nylon toothbrush.

Some other interesting toothbrush facts:

  • The first mass-produced toothbrush was made by William Addis of Clerkenwald, England, around 1780.
  • The first American to patent a toothbrush was H. N. Wadsworth, (patent number 18,653,) on Nov. 7, 1857.
  • Mass production of toothbrushes began in America around 1885.
  • One of the first electric toothbrushes to hit the American market was in 1960. It was marketed by the Squibb company under the name Broxodent.

The toothbrush is an oral hygiene instrument used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles mounted on a handle which facilitates the cleaning of hard to reach areas of the mouth.

Toothbrushes are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard bristled toothbrushes can damage tooth enamel and irritate the gums.[1]


Before the invention of the toothbrush a variety of oral hygiene measures had been used.[2] This has been verified by excavations in which chew sticks, tree twigs, bird feathers, animal bones and porcupine quills were recovered.

The predecessor of the toothbrush is the chew stick. Chew sticks were twigs with frayed ends used to brush the teeth[3] while the other end was used as a toothpick.[4] The earliest chew sticks were discovered in SumerMesopotamia in 3500 BC,[4] an Egyptian tomb dating from 3000 BC,[3] and mentioned in Chinese records dating from 1600 BC. The Greeks and Romans used toothpicks to clean their teeth and toothpick like twigs have been excavated in Qin Dynasty tombs.[4] Chew sticks remain common in Africa[5] the rural Southern United States[3] and in the Islamic world the use of chewing stick Miswak is considered a pious action and has been prescribed to be used before every prayer five times a day.[6] Miswaks have been used by Muslims since 7th century.

Modern toothbrush originated in China. The first bristle toothbrush resembling the modern one was found in China. Used during the Tang Dynasty (619–907), it consisted of hog bristles.[7][8] The bristles were sourced from hogs living in Siberia and northern China because the colder temperatures provided firmer bristles. They were attached to a handle manufactured from bamboo or bone, forming a toothbrush.[3] In 1223, Japanese Zen master Dōgen Kigen recorded on Shōbōgenzō that he saw monks in China clean their teeth with brushes made of horsetail hairs attached to an oxbone handle. The bristle toothbrush spread to Europe, brought from China to Europe by travellers.[9] It was adopted in Europe during the 17th century.[10] The earliest identified use of the word toothbrush in English was in the autobiography of Anthony Wood who wrote in 1690 that he had bought a toothbrush from J. Barret.[11] Europeans found the hog bristle toothbrushes imported from China too firm and preferred softer bristle toothbrushes made from horsehair.[3] Mass produced toothbrushes made with horse or boar bristle continued to be imported to England from China until the mid 20th century.[2]

In Europe, William Addis of England is believed to have produced the first mass produced toothbrush in 1780.[9][12] In 1770, he had been jailed for causing a riot. While in prison he decided that using a rag with soot and salt on the teeth was ineffective and could be improved. After saving a small bone from a meal, he drilled small holes into the bone and tied into the bone tufts of bristles that he had obtained from one of the guards, passed the tufts of bristle through the holes in the bone and sealed the holes with glue. After his release, he became wealthy after starting a business manufacturing toothbrushes. He died in 1808, bequeathing the business to his eldest son. It remained within family ownership until 1996.[13] Under the name Wisdom Toothbrushes, the company now manufactures 70 million toothbrushes per year in the UK.[14] By 1840 toothbrushes were being mass produced in England, France, Germany, and Japan.[15] Pig bristles were used for cheaper toothbrushes and badger hair for the more expensive ones.[15]

The first patent for a toothbrush was granted to H.N. Wadsworth in 1857 (U.S.A. Patent No. 18,653) in the United States, but mass production in the United States did not start until 1885. The improved design had a bone handle with holes bored into it for the Siberian boar hair bristles. Unfortunately, animal bristle was not an ideal material as it retained bacteria, did not desiccate efficiently and the bristles were often extricated from their intended fixed insertions. In addition to bone, handles were made of wood or ivory.[16] In the United States, brushing teeth did not become routine until after World War II, when American soldiers had to clean their teeth daily.[12]

During the 1900s, celluloid gradually replaced bone handles.[7] Natural animal bristles were also replaced by synthetic fibers, usually nylon, by DuPont in 1938. The first nylon bristle toothbrush made with nylon yarn went on sale on February 24, 1938. The first electric toothbrush, the Broxodent, was invented in Switzerland in 1954.[17] By the turn of the 21st century nylon had come to be widely used for the bristles and the handles were usually molded from thermoplastic materials.[2]

Johnson & Johnson, a leading medical supplies firm, introduced the "Reach" toothbrush in 1977.[18] It differed from previous toothbrushes in three ways: it had an angled head, similar to dental instruments, to reach back teeth; the bristles were concentrated more closely than usual to clean each tooth of potentially cariogenic (cavity-causing) materials; and the outer bristles were longer and softer than the inner bristles to better clean between teeth[citation needed]. The Reach toothbrush was the first to have a specialized design intended to increase its effectiveness. Other models from other manufacturers soon followed. Each of these had unique design features intended to be more effective than the previous design.

In January 2003, the toothbrush was selected as the number one invention Americans could not live without according to the Lemelson-MIT Invention Index.[19]

Types of toothbrush[edit]

Electric toothbrush[edit]

Main article: Electric toothbrush

It has been discovered that compared to a manual brush, the multi-directional power brush might reduce the incidence of gingivitis and plaque, when compared to regular side-to-side brushing. These brushes tend to be more costly. An electric toothbrush performs rotations of its bristles and cleans hard to reach places. Most studies report performances equivalent to those of manual brushings, possibly with a decrease in plaque and gingivitis.[20] although the electric version can be more comfortable. An additional timer and pressure sensors can encourage a more efficient cleaning process.[21] Electric toothbrushes can be classified, according to the speed of their movements as: standard power toothbrushes, sonic toothbrushes, or ultrasonic toothbrushes. Any electric toothbrush is technically a power toothbrush. If the motion of the toothbrush is sufficiently rapid to produce a hum in the audible frequency range (20 Hz to 20,000 Hz), it can be classified as a sonic toothbrush. Any electric toothbrush with movement faster than this limit can be classified as an ultrasonic toothbrush. Certain ultrasonic toothbrushes, such as the Megasonex and the Ultreo, have both sonic and ultrasonic movements.

Interdental brush[edit]

An interdental or interproximal ("proxy") brush is a small brush, typically disposable, either supplied with a reusable angled plastic handle or an integral handle, used for cleaning between teeth and between the wires of dental braces and the teeth.

The use of interdental brushes in conjunction with tooth brushing, has been shown to reduce both the amount of plaque and the incidence of gingivitis when compared to toothbrushing alone.[22] Although there is some evidence that after tooth brushing with a conventional tooth brush, interdental brushes remove more plaque than dental floss,[23] a systematic review reported insufficient evidence to determine such an association.[22]

The size of interdental brushes is standardized in ISO 16409.[24][25] The brush size,[26] which is a number between 0 (small space between teeth) and 8 (large space), indicates the passage hole diameter. This corresponds to the space between two teeth that is just sufficient for the brush to go through without bending the wire. The color of the brushes differs between producers. The same is the case with respect to the wire diameter.[27]

Passage hole diameter in mm≤ 0.60.7–0.80.9–1.01.1–1.21.3–1.51.6–1.81.9–2.32.4–2.8≥ 2.8


A Sulcabrush is a type of toothbrush used specifically for cleaning along the gumline adjacent to the teeth. The bristles are usually shaped in a pointed arrow pattern to allow closer adaptation to the gums. A Sulcabrush is ideal for cleaning specific difficult-to-reach areas, such as between crowns, bridgework and crowded teeth. End-tufted brushes may also be used around fixed orthodontic appliances, such as braces.

End-tuft brush[edit]

The small round brush head comprises seven tufts of tightly packed soft nylon bristles, trimmed so the bristles in the center can reach deeper into small spaces. The brush handle is ergonomically designed for a firm grip, giving the control and precision necessary to clean where most other cleaning aids cannot reach.[31] These areas include the posterior of the wisdom teeth (third molars), orthodontic structures (braces), crowded teeth, and tooth surfaces that are next to missing teeth. It can also be used to clean areas around implants, bridges, dentures and other appliances.[32]

Chewable toothbrush[edit]

A chewable toothbrush is a miniature plastic moulded toothbrush which can be placed inside the mouth. While not commonly used they are useful to travelers and are sometimes available from bathroomvending machines. They are available in different flavors such as mint or bubblegum and should be disposed of after use. Other types of disposable toothbrushes include those that contain a small breakable plastic ball of toothpaste on the bristles, which can be used without water.[citation needed]

Ecological toothbrushes[edit]

Commonly, toothbrushes are made of plastic. Such brushes constitute a source of pollution.[33][34] In order to reduce the environmental impact, some manufacturers have switched to using biodegradable materials and/or use replaceable heads.[35] In order to avoid plastic altogether alternative toothbrushes on offer consist of wooden handles (often bamboo) and bristles of bamboo viscose or pig bristles.

Adversity of toothbrushes[edit]

Teeth can be damaged by several factors including poor oral hygiene, but also by wrong oral hygiene. Especially for sensitive teeth, damage to dentin and gums can be prevented by several measures[36] including a correct brushing technique.

It is beneficial not to scrub horizontally over the necks of teeth, not to press the brush too hard against the teeth, to choose a toothpaste that is not too abrasive,[37] and to wait at least 30 minutes after consumption of acidic food or drinks before brushing.[36][38] Harder tooth brushes reduce plaque more efficiently but are more stressful to teeth and gum; using a medium to soft tooth brush for a longer cleaning time was rated to be the best compromise between cleaning result and gum and tooth health.[39]

A study by University College London found that advice on brushing technique and frequency given by 10 national dental associations, toothpaste and toothbrush companies, and in dental textbooks was inconsistent.[40]

Hygiene and care[edit]

  • It is not recommended to share toothbrushes with others since besides general hygienic concerns there is a risk of transmitting diseases that are typically transmittable by blood, such as Hepatitis C.[41]
  • After use it is advisable to rinse the toothbrush with water, shake it off and let the toothbrush dry.
  • Bent and worn out bristles of a toothbrush lead to decreased cleaning efficiency. It is therefore recommended to change it for a new one when it appears to be worn out (roughly after 6–16 weeks).[citation needed]
