How Chin and Nose Affect the Position of the Midline of the Smile Teeth

Ideally, your smile teeth should appear in proportion to your gums, with the midline of the upper front teeth forming the midline of your face. The top of your teeth should appear just above the midline of your lower lip, and the smile line should follow the curve of your lower lip. The height of your upper front teeth should meet your lower lip at the midline, which should be centered on your face. This is known as the "tooth reveal."

Angulation of the midline

The angulation of the smile teeth' midline can affect a smile's attractiveness. When designing a smile, it is important to consider the asymmetries of the chin and nose. The midline of the smile teeth is the most common starting point for a smile design. This study was designed to determine if deviated chin and nose affect the perception of the angulation of the midline of the smile teeth.

Researchers studied the angulation of the midline of smile teeth and determined that the higher the angulation, the less attractive the smile was. However, they found no statistically significant difference between males and females. In the study, Saudi dentists and orthodontic residents were more critical of angulating the midline of smile teeth. They suggested that angulation should be limited to the vertical maxilla to avoid causing problems.

Angulation of the midline of smile tooth positions affects the attractiveness of a smile. The angulation degree in the smile teeth' midline can be up to 10 degrees. Most dental professionals consider angulations of more than 10 degrees unacceptable for orthodontic treatment. This angulation level should be assessed in patients with dental problems. In addition, these differences in facial attractiveness make it difficult to compare male and female faces.

Position of the midline about the facial midline

The position of the midline about the facial and dental apex when smiling is a crucial element of good aesthetics. The upper teeth should fill approximately 75 to 100 percent of the space between the upper and lower lip in a full smile. In addition, the midline about these midlines should be parallel to each other or perpendicular to the imaginary line drawn through the corners of the mouth.

The position of the dental midline about the facial midline has not been studied much. However, the nation is second in proximity to the midline. Previous studies used the vermilion border or philtrum as a landmark for facial form, which may compromise the results. Therefore, a study of the proximity of the dental midline to the facial midline would need to consider the effect of this distance on the results of the dental and facial measurements.

Studies have shown that the position of the dental midline about the facial midline affects smile attractiveness. One study included photographs of patients with a slight deviation in the upper dental midline to the left. Other studies focused on other potential discrepancies in the appearance of a smile. In such a study, researchers included facial and intraoral photographs to assess how different groups reacted to midline deviations.

Position of the incisal edge about the surrounding tissues

The position of the incisal edge about the surrounding tissues of the smile teeth is important because it affects the appearance of the smile, the lip and neck muscles, and overall oral health. In addition, the correct placement of the incisal edge sets the smile's proportions and contributes to the emergence of profile and speech. Here are some tips for positioning the incisal edge:

Incident edges must be placed predictably. Generally, dentists want to minimize the incisal edge's prominence so that the smile will be aesthetically pleasing. Unfortunately, in a study involving laypeople and dental professionals, only the perception of 'the most attractive' incisal edge arrangement was statistically significant. However, it is important to note that dental technicians' and professionals' aesthetic preferences are generally similar.

The incisal edge should be placed in a neutral zone during anterior reconstruction. The patient's perioral complex and tongue oppose each other when speaking, which is why this neutral zone must be respected. Inappropriate placement of the incisal edge may create minor speech impediments or discomfort. In addition, patients with incorrect positioning of the incisal edge will complain about muscle fatigue, leading to further complications.

The placement of incisal edges about the surrounding tissues of smile teeth highly depends on a good overbite or overjet between the anterior and posterior teeth. If the overbite and overjet are too small, the anterior teeth cannot meet the incisal edge, and the gap between the two jaws is too wide. This is not always the case, but an appropriate overbite and overjet relationship between the teeth is necessary for good lateral canine guidance.


After a dentist applies veneers to your teeth, you may experience discomfort. In addition, there will be some bonding sensitivity after the procedure, comparable to biting into something cold. The dentist may give you over-the-counter pain medication to help you deal with the discomfort. It's also important to avoid chewing on hard objects, opening packages, or cutting foods with your front teeth. You should also use a mouth guard if you grind or clench your teeth at night or play sports to prevent damage to the veneers.

Before undergoing dental veneers, consider your budget. While dental insurance rarely covers this procedure, it can help you pay off the cost of the treatment. When evaluating whether to get a partial or complete set of veneers, consider all the pros and cons and weigh the costs versus the desired result. Remember, the process is permanent, so it is important to consider your budget when considering veneers. If you are worried about the cost, consider talking to your dentist about the pros and cons of this procedure.

There are two types of porcelain veneers. Composite veneers require less time to complete than porcelain veneers. Composite veneers use composite resin to bond the veneer to the teeth. The veneers are then polished and smoothed to look like natural teeth. Composite veneers can last for several years if cared for properly. However, they are expensive and require a significant time investment. If you decide to get composite veneers, you should know that they may not be a good choice if you have sensitive or decaying teeth.


A beautiful smile can have a profound effect on the way you are perceived. It can boost your confidence and trustworthiness, and it can even make you seem more approachable. However, a smile plagued by decay or injury can leave you looking less than sexy. Consider getting a dental crown or bridge to feel more confident and presentable in social situations. A San Diego cosmetic dentist like Dr. Daniel Stevens can help restore your smile with a beautiful crown or bridge.

While dental crowns are an excellent choice to improve your smile, they don't come cheap. The cost can vary greatly, depending on the materials used and the amount of preparation required to place the crown. The most affordable option is composite veneers, but this option leaves more exposed parts of the tooth vulnerable to new decay. Composite veneers can also cost less but may only last five to seven years and may require a replacement. Porcelain crowns protect all teeth and look just like natural teeth.

Before your dentist can place a crown on your smile teeth, they will need to make an impression on your teeth. A digital or physical impression of your teeth will help the dentist create a crown that fits perfectly. Your dentist will also need to take a mold of your teeth. This mold will be sent to a lab that makes your crown. The lab will create a crown that fits perfectly and matches the color of your teeth. You'll wear a temporary crown until your second appointment when the permanent crown will be placed.

Dental bonding

Dental bonding might be a great solution if you are unhappy with your smile. This treatment can be performed in one office visit and has a natural-looking result. To prepare your teeth for the procedure, your dentist will use a shade guide to match the color of your new composite resin to your natural tooth color. Composite resin is a plastic material that can treat cavities, stop decay, and improve your oral health.

Despite its ease of application, dental bonding does have its limitations. It is best suited for minor cosmetic changes and short-term corrections in areas where the bite pressure is not too great. In addition, bonding materials can chip or break with chewing on hard objects, biting your nails, or even using pens and pencils. For this reason, it's important to follow a good oral hygiene routine after dental bonding.

Dental bonding isn't an ideal treatment for every case despite its versatility. However, many people opt for this cosmetic treatment to improve their teeth. While bonding isn't permanent, it can correct minor flaws and help you feel more confident about your smile. Contact Smiles by the Sea to schedule an appointment. A professional can help you make an informed decision about dental bonding and recommend other treatments to correct your smile imperfections.
