Overbite

1. What is an overbite?

Underbite, also known as underbite or plow face, is a condition where the lower teeth protrude too much compared to the upper teeth. This is one of the serious bite misalignments, not only causing loss of facial aesthetics but also affecting the chewing function of the teeth.

In an underbite, when the mouth is closed, the lower teeth overlap the upper teeth, creating a characteristic facial shape with a protruding chin. This condition can occur at any age, from children to adults, and can significantly affect the patient's quality of life.

2. Causes of overbite

There are many factors that can lead to an overbite:

• Genetics: Jaw structure and tooth development can be inherited from parents. If someone in the family has an underbite, children are at higher risk of developing the same condition.
• Abnormal jaw development: Underdevelopment of the upper jaw or overdevelopment of the lower jaw can lead to an underbite.
• Bad habits from an early age: Habits such as thumb sucking, tongue thrusting, mouth breathing, or prolonged use of pacifiers can affect the development of the jaw and teeth.
• Trauma: Accidents or injuries to the maxillofacial area can cause abnormal development of the jawbone.
• Early tooth loss: Early loss of baby teeth can affect jaw development, leading to an overbite.
• Birth defects: Certain birth defects such as cleft palate can increase the risk of an overbite.

3. Signs of an overbite

To recognize an overbite, you can pay attention to the following signs:

• Protruding chin: When viewed from the side, the chin will protrude further forward than normal.
• Protruding lower front teeth: When biting, the lower front teeth will be in front of the upper front teeth.
• Difficulty chewing: The patient may have difficulty biting and chewing food because the teeth do not fit properly.
• Poor pronunciation: Abnormal tooth position can affect the ability to pronounce words, especially the “s” and “t” sounds.
• Concave face: The midface may appear concave due to underdeveloped upper jaw.
• Uneven tooth wear: Due to improper bite, some teeth may wear down faster than normal.

4. Types of overbite

Overbites can be classified into two main types:

• Dental overbite: In this case, the jaw structure is normal, but the teeth are in the wrong position. Usually occurs in the incisors or premolars.
• Skeletal underbite: This is a more serious case, where the upper jaw is underdeveloped or the lower jaw is overdeveloped. This type often requires surgical intervention to treat.

5. Harmful effects of reverse bite

Overbite not only affects aesthetics but also causes many health problems:

• Difficulty chewing: Teeth that do not fit together properly make it difficult to bite and chew food.
• Uneven tooth wear: Uneven pressure on teeth can lead to premature tooth wear.
• Temporomandibular joint pain: Abnormal tooth position can put stress on the temporomandibular joint, leading to pain.
• Speech problems: An underbite can affect the ability to speak clearly.
• Self-consciousness about appearance: Changes in facial shape can affect a person's self-confidence.
• Increased risk of gingivitis and tooth decay: Due to difficulty in oral hygiene.

6. Treatment of overbite

Treatment for an overbite depends on the cause, severity, and age of the patient. Common treatments include:

• Braces: This is a common method of correcting tooth position, especially effective for dental overbites.
• Orthognathic surgery: In cases of skeletal overbite, surgery may be necessary to correct the position of the jaw.
• Use of orthodontic appliances: Devices such as reverse face masks or Frankel frames can be used to stimulate the growth of the upper jaw in children.
• Porcelain crowns: In some mild cases, porcelain crowns can help improve the shape and position of teeth.
• Combining methods: Many cases require a combination of braces and surgery to achieve optimal results.

7. How to prevent overbite

Although it is not possible to completely prevent an overbite, especially in cases where it is genetic, there are a number of measures that can help reduce the risk:

• Regular dental checkups: Regular dental checkups help detect bite problems early.
• Limit bad habits: Help children quit habits like thumb sucking or tongue thrusting.
• Baby Teeth Care: Keeping baby teeth healthy helps guide permanent teeth into the correct position.
• Early intervention: If signs of an overbite are detected in a child, early intervention may yield better results.
• Treat respiratory problems: Addressing problems such as adenoids or difficulty breathing through the nose can help prevent mouth breathing.

8. Frequently asked questions about overbite

Question 1: Can an overbite heal on its own?

Answer: An underbite usually does not resolve on its own, especially when the cause is skeletal. Medical intervention is necessary for effective treatment.

Question 2: How long does it take to treat an overbite?

Answer: Treatment time depends on the severity and method used. Braces can take anywhere from 18 months to 3 years, while surgery may require additional recovery time.

Question 3: Can an overbite be treated in adults?

Answer: It is possible to treat an overbite in adults, however it can be more complicated and often requires a combination of methods.

Question 4: Does an overbite affect overall health?

Answer: Yes, an underbite can affect your oral health, ability to chew, and even mental health due to cosmetic issues.

9. Conclusion

An overbite is a serious dental problem that requires prompt attention and treatment. Understanding the causes, symptoms, and treatment options will help you get a comprehensive view of the condition. If you suspect that you or your child has an overbite, seek advice from a dentist as soon as possible. Early treatment will not only improve aesthetics but also prevent possible complications in the future.
