The Truth About Enamel Repair"},"content":{"rendered":"\n

No toothpaste can grow completely new tooth enamel once it has been physically worn away or destroyed by a cavity. However, fluoride toothpaste can help strengthen weakened enamel and support the replacement of minerals during the earliest stage of tooth decay. This process is called remineralisation. It is different from regrow enamel. Remineralisation may strengthen areas that have begun losing minerals, but it cannot restore a hole in the tooth, rebuild a chipped edge or replace enamel that has been lost through advanced erosion. Understanding this difference can help you evaluate \u201cenamel repair\u201d claims and recognise when toothpaste may help\u2014and when you need treatment from a dentist.<\/p>\n\n\n\n

What is Enamel?<\/h4>\n\n\n\n

Enamel is a hard, glossy, it layer that forms the outside covering of your teeth. This substance also makes up the inside of your teeth, which is known as dentin. According to the American Dental Association (ADA), enamel is the hardest natural substance<\/a> in the human body and is eight times more resistant to fracture than tooth dentin. This is why your teeth can withstand a lot of pressure and put up with daily wear and tear.<\/p>\n\n\n

The enamel on your teeth is a very thin layer covering the crown of your teeth. This hard and shiny substance protects the tooth from wear and tear. It is made up of approximately 95% calcium and 5% other minerals, such as phosphorous, fluorine, magnesium, and potassium. This means that outer layer or glaze is very important in keeping your teeth healthy.<\/p>\n\n\n\n

Why Can Tooth Enamel Not Grow Back?<\/h4>\n\n\n\n

Enamel is the hard outer covering of the tooth and is the hardest substance in the human body. Unlike skin or bone, mature enamel does not contain living cells that can reproduce and rebuild damaged tissue. Once enamel is physically lost through decay, acidic erosion, aggressive brushing, grinding or trauma, the body cannot manufacture a new layer of enamel. This is why protecting the enamel that remains is so important.<\/p>\n\n\n\n

What Is Enamel Remineralisation?<\/h4>\n\n\n\n

Throughout the day, tooth enamel continually loses and gains minerals. Acids produced by plaque bacteria and acids from food and beverages can remove minerals such as calcium and phosphate from the enamel. This is known as demineralisation. Saliva helps neutralise acids and returns minerals to the tooth surface. Fluoride can support this natural repair process and make the enamel more resistant to future acid attacks. This strengthening of early mineral loss is called remineralisation. Remineralisation is most useful before a physical cavity or hole has formed.<\/p>\n\n\n\n

The purpose of toothpaste is to clean your teeth and help remove plaque, which is composed of bacteria, from your teeth which helps prevent cavities<\/a> and tooth decay.<\/strong><\/p>\n<\/div><\/div>\n\n\n\n

How Does Fluoride Toothpaste Strengthen Enamel?<\/h4>\n\n\n\n

Fluoride toothpaste helps protect enamel in several ways. It can reduce mineral loss, encourage minerals to return to weakened areas and make the repaired surface more resistant to acid. Using fluoride toothpaste regularly may help arrest or reverse very early decay, particularly when it appears as a chalky white spot without a physical cavity. The result depends on the severity of mineral loss, oral hygiene, saliva, diet and how frequently the teeth are exposed to sugar and acid.<\/p>\n\n\n\n
