When you look at teeth from the front – think of looking at yourself in the mirror – a perfect bite will feature upper front teeth that are lined up parallel to your lower lip when you smile. When you close your bite, about half to two-thirds of the length of your bottom teeth should be easily visible.
FROM THE FRONT: your upper front teeth should fall in front of your lower teeth (toward your lip), and should overlap them by about 2 mm. Upper and lower front teeth should hit lightly. FROM THE TOP (OR BOTTOM): The back teeth should be upright, NOT tipped toward the cheek or tongue.
Should top teeth overlap the bottom teeth? There should be a little overlap of the top and bottom teeth at the front of your bite—usually around 4mm. But you should still be able to see 90% or around of your bottom teeth. Any less and you may have what is known as a 'deep' bite.
Different types of teeth
These are: Incisors – the flat teeth at the front of the mouth, which help you bite into food and pronounce words. Canines – the sharp teeth behind the incisors that grip and tear food. Premolars and molars – the large, rectangular teeth towards the back of the mouth that chew and grind food.
Ideally, the edges of the upper front teeth should parallel the top of the lower lip. If the upper teeth are too long, the patient will show too much gum tissue when they smile. If they are too short, they won't show enough enamel when they smile and they will look prematurely old or toothless.
Resting teeth means they are sitting dormant and it also means they're not interacting with anything else like food, your tongue, or each other. The standard resting position has the teeth not touching each other; when the mouth is closed the teeth are slightly apart.
Healthy teeth are white or slightly off-white in color, with smooth surfaces and well-defined edges. They should also be free of chips, cracks, and visible cavities. The gum tissue surrounding the teeth should be pink and firm, with no signs of inflammation or bleeding.
When enamel wears away, or if it never forms properly, the teeth can take on a dull, translucent, or waxy appearance. This means that if your teeth are starting to look transparent, your enamel around the edges of your teeth where dentin does not extend is worn.
Symptoms of tooth decay
tooth sensitivity – you may feel tenderness or pain when eating or drinking something hot, cold or sweet. grey, brown or black spots appearing on your teeth. bad breath. an unpleasant taste in your mouth.
Genetic and environmental factors can affect the development of teeth including the size and shape. Misshapen teeth may be isolated to one tooth or may occur as part of a widespread condition throughout the mouth. Common misshapen teeth include wisdom teeth, second premolars, and upper lateral incisors.
The edges of the upper front teeth should run parallel the top of the lower lip. If the upper teeth are too long, you'll show too much gum tissue when you smile. It makes you look gummy. If they're too short, you won't show enough tooth and that makes you look old.
You may not have realized this, but teeth are not meant to touch. It sounds odd, but think about it. They don't touch while you speak, smile or rest. Even when you chew, your teeth only have to be close enough to mash food, not necessarily touch.
Your upper teeth should fit slightly over your lower teeth and the points of your molars should fit the grooves of the opposite molar. If your jaw lines up like this, you most likely have a healthy bite. When you have a healthy bite it improves the function of your teeth, it also balances your teeth.
Proper oral posture means that at rest the tongue is to the roof of the mouth, the teeth are touching or slightly apart, and the lips are together without strain.
A small piece can be repaired with a bonded filling. A larger fracture could require a root canal treatment, a crown, or a veneer for stability.
As a person gets older, the white enamel on their teeth becomes worn. When this happens, the calcified tissue underneath starts to show through. This tissue is called dentin, and it has a yellowish color.
Uneven teeth can be caused by a variety of factors. For example, genetics, poor oral hygiene, teeth grinding, age, and accidents can all lead to an uneven smile. You may think of your uneven teeth as a purely cosmetic issue. However, uneven teeth can result in other dental issues.
Dental Filling or Bonding
If the repair is to a front tooth or can be seen when you smile, your dentist will likely use a procedure called bonding, which uses a tooth-colored composite resin. Bonding is a simple procedure that typically does not require numbing the tooth.
The ridges appear when permanent teeth start growing at a young age. Mamelons are formed from the enamel, which fuses together when a child's teeth are developing underneath their gums. A child's front teeth are formed as lobes that are fused before they break through the gum tissue.
Teeth have a black/ dark spot
Dark spots on or over your teeth indicate that they are decaying. If you notice any discolouration, you should see a dentist as soon as possible. If left untreated, blackened teeth will cause decay to spread throughout a single tooth and may even spread to other teeth.
Non-White or Yellow Teeth are Unhealthy
Teeth whitening treatments usually work by stripping or entering the outer enamel layer, which makes teeth weaker if done many times. So, more often than not, yellow teeth are actually stronger than pearly white ones–so long as they're cleaned regularly.
When the enamel is eroded so badly, in its thinnest form your inner layer can be seen, dentin. Dentin has a natural yellow color. So, if your enamel is transparent enough to show your dentin, your teeth look yellow even if you brush them every day.
Symptoms of Bite Being Off
Physical appearance. his is the most obvious symptom that your bite is off. Teeth may appear crooked, twisted, or otherwise asymmetrical. This can result in uneven wear on the surface of your teeth, as well as pain and sensitivity.
