What are the requirements for a beautiful set of teeth?

Many people who want to start orthodontic treatment think, "I want to have beautiful teeth!" and many of them will start treatment with this in mind.

So what does "beautiful teeth" look like?

Possible in orthodontics and cosmetic dentistry,We will discuss the requirements for a beautiful and ideal set of teeth.

Conditions for a beautiful and ideal set of teeth

A clean and ideal set of teeth is,The condition of the teeth and gums is determined by observing the mouth from the following four points

• Condition of teeth and gums when biting down
• Teeth, gums and lips visible when smiling
• Shape of mouth when viewed from the side
• Dental cleanliness

Condition of teeth and gums when biting down

Ideally, when you look in the mirror and bite your teeth together from the front, your teeth and gums should look like the following.

• The upper and lower midlines are aligned.
• The upper front teeth cover the lower front teeth by about 2-3 mm.
• Balanced length of the six upper front teeth
• Adjacent teeth do not overlap.
• Uniform border line between gums and teeth.
• No black triangle.
• Symmetry in tooth size, orientation, and shape
• Baccaric corridors (shadows at the corners of the mouth when smiling) are not noticeable.

The upper and lower midlines are aligned.

There are seven to eight permanent teeth on each side, symmetrically arranged around the midline. The median line is the line between the first tooth from the front and the tooth that serves as the reference for symmetry.

In a clean set of teeth,Ideally, the midline of the upper and lower teeth should be vertically aligned straight.

The upper front teeth cover the lower front teeth by about 2-3 mm.

The beautiful teeth are,Ideally, the upper teeth should cover the lower teeth by 2 to 3 mm.

If the upper teeth cover the lower teeth more than this, it could be an "overbite" or "bucktooth (maxillary protrusion)," conversely, if the lower teeth cover the upper teeth, it could be a "passive mouth (mandibular protrusion)," and if the upper and lower teeth are not in contact, it could be an "open bite.

Balanced length of the six upper front teeth

A good balance of the length of the six upper front teeth (from the front teeth to the canines) gives the appearance of a good alignment of the teeth.

The ideal balance is for the first tooth from the front (central incisor) and the tip of the third tooth (canine) to be about the same length in line, with the second tooth (lateral incisor) being slightly shorter.

Adjacent teeth do not overlap.

One tooth does not grow forward or backward or at an angle to the adjacent tooth,Teeth look better when adjacent teeth are aligned straight.

Teeth that overlap each other and have uneven dentition are called "plexus," "messed-up teeth," or "uneven teeth.

Uniform border line between teeth and gums.

If the border line between the teeth and gums is a uniform line, with the image of the line parallel to the tip of the teeth, the teeth will look good.

If the gums are significantly receding in one area due to periodontal disease or other reasons, the gum line will not be uniform, making the teeth appear longer in one area and slightly less esthetic.

No black triangle.

A black triangle is a triangular gap that forms at the base of adjacent teeth. It is called a black triangle because it appears to be a black gap without light.

Gums are inserted in a triangle between teeth, and no gaps are considered clean gums, but aging, periodontal disease, and orthodontic treatment can cause black triangles to form.

Black triangles of a certain size can form in anyone as they age. However,As the black triangle grows, estheticsThis can lead to a decrease in

Symmetry in tooth size, orientation, and shape

The shape of the teeth varies from person to person,When the size, direction, and shape of the teeth are symmetrical with the midline as the border, the teeth look beautiful.

Teeth, gums and lips visible when smiling

Ideally, when smiling with the corners of the mouth lifted, the following two conditions should be met

• Smile lines line the lower lip.
• Gums of upper front teeth not too visible

Smile lines line the lower lip.

The line connecting the tips of the upper front teeth is called the "smile line.

When smiling with the corners of the mouth lifted, a smile line along the lower lip is a good sign that the teeth are well aligned.

Gums of upper front teeth not too visible

Ideally, when smiling, the upper lip should slightly hide the border between the teeth and gums.

A "gummy smile" occurs when the upper lip rises and more than 3 mm of gum is visible when smiling.

Buckaroo corridor is inconspicuous.

Baccaric corridors are shadows that form at the corners of the mouth when smiling, and the larger these shadows become, the darker the mouth appears.

Not only the alignment of the teeth themselves, but also the relationship between the teeth and mouth is important for a beautiful appearance.

Shape of mouth when viewed from the side

The line connecting the nose and the tip of the chin is called the "E-line. It is also called the "elastic line" and is considered the standard for a beautiful profile in cosmetic surgery.

The E-line is sometimes used in dental treatment to evaluate the protrusion of the mouth, and ideally, when looking at the face from the side, the mouth should be tucked inside without touching the E-line.

However, the E line was created based on Westerners with high noses, so there are few Japanese with genetically different skeletal structures who fit this description.

For Japanese, the ideal is for the lips to lightly touch the E line.

Dental cleanliness

Well-maintained, clean teeth are very important for a beautiful set of teeth, including

• No plaque or tartar on teeth
• No periodontal disease or caries
• Teeth not yellowed by staining or yinning

Even if all the requirements for a beautiful set of teeth are met,If the mouth is filthy, everything is ruined.

No plaque or tartar on teeth

It is very important that daily tooth brushing is done correctly and that there is no plaque or tartar on the teeth.

Plaque and tartar on the teeth can cause not only tooth decay and gum disease, but also yellowing of the teeth and other oral problems.

No periodontal disease or caries

It is important for clean teeth to be free of cavities and periodontal disease, as this reduces esthetics.

Periodontal disease causes gum recession as the bone supporting the teeth dissolves.

Gingival recession not only creates black triangles and causes esthetic deterioration,This can cause bad breath and tooth loss.

In addition, tooth decay causes teeth to dissolve and darken, which reduces esthetics.

Teeth not yellowed by staining or yinning

If there is a lot of staining or yin on the teeth, the teeth will become yellowish and less clear.This can give the impression of being unclean and aged.
