Introduction
Toothpastes typically consist of:
Mild abrasives to brush off any unwanted particles and light stains. Examples of abrasives include calcium carbonate, dehydrated silica gels, hydrated aluminum oxides, magnesium carbonate, phosphate salts and silicates.
Fluoride to strengthen tooth enamel and remineralize enamel in the early stages of tooth decay.
Humectants to prevent water loss in the toothpaste. Examples include glycerol, propylene, glycol and sorbitol.
Flavoring agents, such as saccharin and other sweeteners improve taste
Thickening agents or binders to keep the toothpaste together. They include mineral colloids, natural gums, seaweed colloids or synthetic cellulose.
Detergents to create foam. They include sodium lauryl sulfate, sodium

People vary considerably in their tendency to form and accumulate dental stains and surface debris—as well as in their desire for white teeth. It has been long recognized that brushing with just a wet brush has little influence on stain removal within the typical one to three minutes of twice daily brushing. Depending to some extent upon toothbrush bristle texture and the individual’s oral tissues, longer brushing times merely irritate the gingival tissues without achieving the desired tooth surface cleansing.
The three major categories of toothpaste abrasives are phosphates, carbonates, and silicas.
• Phosphates are used as part of toothpaste formulas because they help the product to leave the teeth looking white and feeling clean.
• Dicalcium phosphate dihydrate (DCPD)
The Lever toothpaste ad campaign of the 1940s made this material famous with the slogan, “Makes the yellow go away.”
• Calcium pyrophosphate (CalPyro)
CalPyro is used in a toothpaste with stannous fluoride. The calcium pyrophosphate used was heat treated to reduce the soluble calcium ion availability and thus increase the fluoride ion
Thesis Statement: Concerns for water fluoridation stem from the toxicity of fluoride, the dangers fluoride pose to the body, and equal declining tooth decay seen for fluoridated and non-fluoridated countries.
All water sources, whether fresh or salt, have varying levels of fluoride (Awofeso, 2012). Around 1945 it was discovered that communities with higher rates of naturally occurring fluoride had lower rates of tooth decay (Dean, 1938) which resulted in the addition of artificial fluoride to public water supplies. The incidence of tooth decay fell drastically in fluoridated communities as a result, leading to widespread adoption of public water fluoridation as a public health strategy.

Crest began in the early 1940’s when Procter & Gamble (P&G) began their research to find ingredients to add to toothpaste to lesson tooth decay. Dental disease was one of the most prevalent hea...
Saliva is a protector of your teeth. Increase the production of it by consuming foods that contain a lot of fibers.
The main problem concerning the durability of resin-dentin is the hydrolytic degradation of the two components of the hybrid layer. These are the collagen matrix and the adhesive resin [8]. Many approaches to enhance long-term bonding were developed , these include the inhibition of dentinal endogenous proteases (matrix metalloproteinases and cysteine cathepsins)[22].Matrix metalloproteinases are thought
In answering the PICO question, silver diamine fluoride is more effective at arresting dentinal caries than sodium fluoride varnish. In reviewing these research studies, SDF is an affordable, effaceable alternative to restorative treatment that can be particularly helpful in areas without much dental personal, equipment, or facilities. Further study is needed to determine the recommended interval, exact application, and longer term outcomes. In conclusion, research suggests SDF would be a great carries treatment solution for people around the world, especially those in disparity groups.
Dental sealants are composed of plastic as a result, they will eventually wear down with use. However, eating hard foods can speed

Well what does fluoride do for teeth when being consumed and applying to teeth? Fluoride has a great importance in the protection and development of teeth. Fluoride helps protect teeth in many ways. First, for the protection against demineralization, which is when the bacteria in your mouth combine with sugars that produce acid, and it’s this acid that can erode tooth enamel and causes damage to teeth (Nordqvist 4). This damage is the lose of tooth enamel which is when minerals are lost from the enamel layer when acids are formed (Dental 1). Second, is remineralisation, which is what rebuilds the teeth’s enamel. How this works is fluoride,
It is a base of electrostatic molecules forming together as one while cured so that it gives you that sleek and finishing look of being new and turning old or any item into something brand new.
Tooth brushing techniques causing gingival trauma are a significant factor for gingival recession. The frequency, duration and force of brushing all contribute to recession. Excessive force and improper technique may lead to ...
This is an example of a soap molecule. The hydrocarbon end is non polar and hydrophilic (water hating) and the carboxylate end is polar and hydrophilic (water loving). This the property which allows it to clean, it acts as an emulsifying agent. The soap disperses in water to form miscelles where a negatively charged surface is formed and hydrocarbon chains are in the centre. These miscelles surround droplets of dirt or grease suspending them in the water so they can be washed away.
“Tooth powder” or toothpaste in the form of powder, was developed during the 19th century. In 1855, the Farmer’s Alamanac cited the ingredients of a common tooth powder, which included honey, green sage, and myrrh. In
Titanium isopropoxide and acetic acid were added in in a 1:1 molar ratio along with a non-ionic surfactant in 2-propanol. An opalescent homogeneous gel was obtained which was aged and peptized and finally underwent hydrothermal
