What Are Molar Teeth?

Molar teeth, located near the back of your mouth, feature flat surfaces with elevations known as cusps for grinding food during chewing.

Children typically first see permanent teeth appear around age six. Premolars or bicuspids erupt between 11-13.

Defective baby molars can lead to greater issues with your dental health in later life. If left untreated, they could cause adjacent teeth to shift out of place, potentially creating an undesirable crookedness in your smile.

They are the largest teeth in the mouth

Molars are flat teeth located at the back of your mouth with numerous cusps or divots on top. Used for grinding food into manageable pieces that can easily be swallowed and digested, people typically possess six upper and six lower molars in total; usually poking through around age six while more typically appearing between 17-25.

Enamel is the hard, white material covering the outermost surface of a tooth that serves to protect its inner parts from damage and decay. Teeth are connected by roots that extend into jaw bone beneath gumline for support; there are four major varieties: Radicular, Mesiobuccal Buccal and Distobuccal that play different roles for supporting their respective functions of the tooth.

Next are the incisors, which are pointed teeth on both sides of the mouth that serve as the sharpest teeth for cutting food into smaller pieces. Premolars come next and feature flat surfaces that crush food into smaller chunks; most adults possess eight premolars.

Molars, which are the largest teeth in the mouth, have broad surfaces for chewing food and helping maintain facial structure. Most adults possess 12 molars — six on top and six below — spread throughout their jawline.

Although molars are essential for chewing food, their misalignment can create serious dental issues. An incorrect alignment could lead to cracked or fractured teeth as well as painful bites; an orthodontist can assist in correcting their alignment so as to help avoid further dental issues and ensure proper occlusion.

The third molars, also referred to as the permanent dentition, usually appear between 5 and 7 in children as part of the permanent dentition. Although larger than incisors and premolars, third molars lack as many cusps resulting in them exerting pressure on surrounding teeth and jaw bones when they erupt and may lead to an issue known as an “impacted wisdom tooth,” which must be removed surgically.

They are responsible for chewing food

Molar teeth are the workhorses of your mouth, responsible for breaking down food into something easily swallowed. With numerous cusps on their occlusal surface designed to break apart food into bite-size chunks and resisting forces of chewing to maintain their shape for as long as possible, these molars are an integral part of maintaining dental health and wellness. You have 12 of them total – three sets in each jaw (called first, second and third molars).

The longest, flattest molars in your mouth are known as premolars or bicuspids and help tear and split food before it heads towards the main molars for grinding. A full grown adult typically has eight of these premolars which typically appear around the same age as canines.

Following canines come the incisors, which resemble fangs with sharp points at their ends and serve to tear food and break apart larger chunks. Children typically get their first permanent incisors between 6 and 7. Next are canines; which are the shortest teeth in your mouth with pointed ends similar to incisors but less hard than their counterparts (molars). Canines can also be used for tearing food apart, although not quite as efficiently.

After canines come the molars, which contain more ridges and grooves to aid them in grinding food, as well as multiple cusps designed to shear and crush it. Lower molars have trigonids on buccal/labial sides while upper ones possess metaconids with anterior paraconid basins and posterior paraconid basins to form an effective crushing system similar to mortar and pestle.

Molars play an essential part of our digestive process, yet often lack sufficient attention or care. This can result in cavities, gum disease and other issues; so it is essential that we brush and floss regularly as well as visit our dentist at least twice annually so as to maintain healthy molars.

They are the last teeth to develop

Molars are flat teeth at the back of your mouth with multiple small points (cusps) for crushing and grinding food, as well as for chewing it into manageable portions for easier swallowing. Their name comes from Latin words mola (millstone) and dens (tooth). Molars can be found both upper and lower jaws; with each jaw having six upper molars and six lower molars.

At around age 6 to 7, once all deciduous teeth have fallen out, permanent molars begin to appear as permanents – premolars first then premolars (commonly referred to as wisdom teeth). After 11-13 years old, second molars (commonly referred to as premolars), followed by third molars – commonly referred to as wisdom teeth) start appearing. Some individuals never have their wisdom teeth erupt while others opt to remove them surgically due to lack of space or crowding issues.

Adult teeth will contain 32 permanent molars – four in each jaw. Molar development begins during embryogenesis as thin translucent nubs that gradually transform into solid opaque teeth; their formation depends upon multiple factors including environment, genetics and oral health considerations.

Every tooth contains one to three roots; the largest molars typically feature two to five roots, while premolars and canines only need one root each. Molar roots tend to be thicker and wider than their counterparts.

Outside of shape and structure differences, molars share similar features. They’re generally flat with raised points called cusps for grinding food into soft liquid forms; chewing and churning food to achieve soft consistency; helping maintain facial structure as they maintain face structure – not to mention helping keep other teeth aligned properly! Although difficult to remove from your mouth entirely, molars must be done so for their own good; otherwise they could potentially interfere with other teeth’s alignment and pose health risks to other members.

They are susceptible to tooth decay

No matter if they are permanent or baby teeth, molars have many features that make them particularly prone to tooth decay than other teeth. This includes their deep grooves, fissures and nooks on their chewing surfaces which tend to trap food debris, bacteria and make cleaning them difficult. These irregularities also interfere with remineralizing tooth enamel following eating or drinking, and may contribute to cavities. Tooth decay occurs when natural bacteria in your mouth interact with carbohydrates found in food and beverages to produce acids which attack tooth enamel and cause decay. These acids cause enamel to weaken and break down, and if they remain on the surface for too long they could begin eroding dentin and creating cavities in your tooth. Molars are particularly prone to tooth decay because they can be hard to reach when brushing, with deep grooves collecting food debris, bacteria and acidity from food sources. Succulent foods like gummy bears or raisins may lead to further decay when consumed regularly, and cannot be removed with brushing alone. Therefore, using an interdental cleaner like an Oral-B interdental brush or Reach Stim-U-Dent and regularly rinsing with fluoride rinse can help preserve healthy molars and ensure their ongoing good health.

Once a cavity has been detected, a dentist can use dental filling material to restore damaged areas and relieve pain or discomfort. For severely decayed molars however, a root canal or crown may be necessary – while for children’s decayed molars a laser treatment may be more suitable as no anesthetics or high-speed handpieces need be required – however this option would still need approval by parents before beginning.

Preventing tooth decay is top priority for both dentists and their patients alike. Regular brushing, flossing, and fluoride rinse use can help protect teeth against cavities; however it may not always be enough. Molars in particular are susceptible due to deep grooves that trap food; however with good oral hygiene practices such as regular dental visits, sealants, fluoride treatments, dietary support, sealants and nutritional awareness strategies you can significantly lower the risk of cavities in molars.
