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.
Your bite viewed from the front
Ideally, the edges of the upper front teeth should parallel the top of the lower lip.
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.
While clenching your teeth together, the top and bottom front teeth should overlap slightly. The Side: At the side, your teeth should lock easily in together like cogs in a wheel. The top teeth should sit just on the outside of the bottom teeth, so they fit snugly together.
With the teeth together, you would expect the upper teeth to sit on the inside of the lower lip. If they sit over the lower lip, this might be a sign of protruded teeth. A person with protruded teeth is more at risk of tooth damage or loss from accidents and may have speech or eating problems.
Formulating the Perfect Smile
The upper and lower lip should both be symmetrical, and their centres should meet at the midline of the face. All teeth should be straight. The top teeth should be dominant; while smiling, little to nothing of the bottom teeth should be shown.
Your top teeth should sit in front of your bottom teeth. This allows the top molars to join together correctly with your bottom molars, and enables your teeth to cut through your food when you chew it.
Actually, your tongue should be resting entirely on the palate. Not just the tip of the tongue, but the middle and posterior sections should be resting up. Your lips should be together, and your breathing should be through the nose 95-100% of the time.
Common Signs Of Crowded Teeth
Overlapping teeth. Difficulty chewing. Difficulty flossing between your teeth. Crooked teeth.
The pointed ends of the top teeth should fit perfectly between two teeth in the bottom. The backs of the upper front teeth should rest in gentle contact with the fronts of the lower ones. Essentially, your bite should “close”. If your front upper teeth stick out past your lower teeth, this is called an overbite.
The extent of incisal tooth display at rest is an important esthetic factor in evaluating the outcome of fixed and removable prosthodontic procedures [1]. Accepted prosthodontics guidelines recommend displaying 2–4 mm in the arrangement of upper incisor teeth below the relaxed lip [2].
The upper teeth smile line should generally follow the curve of the lower lip. The central teeth should have a balanced width-to-length ratio. The edge of your bottom teeth should be parallel to your lower lip when you smile.
Front teeth that do not touch, or anterior open bites, are a fairly common problem in Orthodontics. There are many underlying causes, from muscular imbalances, skeletal growth problems, finger habits, and tongue habits.
Thus, longer front teeth are associated with youth, warmth and thus sex appeal. This is a good smile to choose if you have an attractive nose, sharp chin, and prominent lips, as the longer incisors draw attention to those areas of the face. Also, if you want to appear younger, longer central incisors are recommended.
When we say bite, what we're talking about is the way your upper and lower jaw come together. 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.
If your wisdom teeth are growing in properly, you won't feel any significant pain or discomfort near the rear of your mouth. If you do, this could be a sign that your wisdom teeth are coming in improperly, or are becoming infected – and you should have them pulled right away.
Here are the possible causes why your teeth don't show when you smile: Your teeth are too small. You have an underbite/overbite. You have a long upper lip.
Teeth naturally tighten themselves back up over a short period of time. If the affected tooth does not firm -up itself then you need to make an appointment at your dentist for an examination. Regular hygiene appointments will decrease the likelihood of your teeth getting loose.
Proper oral resting posture is achieved when the following is present: mouth is closed with teeth touching (or just slightly apart) lips are closed. tongue is resting on the roof of your mouth (the hard palate)
In a healthy mouth, the tissues are pink, firm and moist. If you have a healthy mouth, your breath will smell pleasant or neutral. Healthy gums are firm and pink, not red or white. They are not swollen or sore.
A tongue thrust condition is sometimes called an orofacial (mouth and face) myofunctional (muscle function) disorder (OMD). The tongue may lie too far forward during rest or protrude between upper and lower teeth during speech, swallowing, and at rest.
When you're resting your mouth, ideally your jaw will form a perfect bite. This is when your upper and lower teeth touch lightly. Your upper front teeth (or incisors) should come down slightly in front of your lower front teeth, and the grooves on your back teeth should align.
The Duchenne smile. This one is the gold standard. The Duchenne smile is also known as the smile of genuine enjoyment. It's the one that involves the mouth, the cheeks, and the eyes simultaneously.
