Invisalign and underbites
A good treatment option for minor to moderate underbites is Invisalign. When the bottom teeth stick out further than the upper teeth, the lower jaw juts forward and is said to have an underbite.
A series of individually created, removable aligners called Invisalign are used to progressively move the teeth into their appropriate places.
Here’s how Invisalign can help with underbites:
- Alignment: Invisalign aligners gently shift the teeth into alignment by applying small, controlled stresses. This can lessen the severity of the underbite by addressing the mismatch between the upper and lower teeth.
- Bite correction: In addition to straightening teeth, Invisalign can aid in correcting the bite. The upper and lower arches’ bite relationship will be improved as a result of the aligners’ gradual positioning of the teeth and jaws.
- Aesthetics: A discrete substitute for traditional braces to treat underbites, Invisalign aligners are translucent and nearly invisible when worn. This may be especially tempting to people who want a discrete orthodontic treatment option.

Here’s how braces can help with underbites:
- Alignment: Braces are bonded to the teeth and include brackets, wires, and other orthodontic components. To gradually realign the teeth, regulated stresses are applied to the wires on a regular basis. This lessens the severity of the underbite by addressing the mismatch between the upper and lower teeth.
- Bite correction: In addition to straightening teeth, braces can assist in correcting the bite. Braces can direct the growth and development of the jaws, putting them into a more harmonic position by applying pressure to the teeth and jaws. The upper and lower arches’ biting connection is improved as a result.
- Treatment customization: Every underbite is different, and the treatment strategy for braces is individualised to meet the needs of each patient. Orthodontists carefully assess the severity of the underbite and create a treatment plan that may include various braces, including clear aligners, ceramic braces, and classic metal braces. They also take into account any extra orthodontic devices that could be required to adequately treat the underbite.
Surgery and Underbites
In some cases, surgery may be recommended as a treatment option for underbites that cannot be corrected through orthodontic treatment alone. Underbite surgery, also known as orthognathic surgery, involves repositioning the jaws to improve the alignment of the teeth and the overall bite.
Here are some key points about surgery for underbites:
- Evaluation and planning: An oral and maxillofacial surgeon does a thorough evaluation before considering surgery. To assess the severity of the underbite and choose the best course of action for treatment, this evaluation also involves taking precise X-rays, pictures, and impressions of the teeth and jaws.
- Orthodontic preparation: Most patients receive orthodontic treatment for a time before surgery. This entails utilising braces or other orthodontic devices to move the teeth into the best alignment possible in order to lay a solid basis for surgical repair.
- Surgical procedure: Under general anaesthesia, underbite surgery is normally carried out at a hospital or surgical facility. To reach the jawbones during the treatment, the surgeon creates small incisions inside the mouth. Then, they move the jaws into their new places by cutting the bones and usually using plates, screws, or wires to hold them in place. Dissolvable sutures are used to seal the cuts.
- Recovery and post-operative care: After underbite surgery, patients can anticipate some swelling, bruising, and discomfort. Recovery and post-operative care. During the first stage of recuperation, doctors typically recommend pain medication and a soft-food diet. It’s crucial to adhere to the post-operative instructions given by the surgeon, including dietary restrictions and oral hygiene guidelines. To track the healing process and make any required adjustments, routine follow-up visits will be planned..
Children and underbites
Underbites can also occur in children, and it’s important to address them early to ensure proper development of the jaws and teeth.
Here are some key points to consider regarding underbites in children:
- Early evaluation: Around the age of 7, it is advised to have a child examined by an orthodontist or a paediatric dentist. This makes it possible to identify underbites and other orthodontic problems early on. Early assessment aids in determining whether assistance is required and, if so, what the best course of action would be.
- Orthodontic therapy: Orthodontic therapy is frequently effective in treating children’s underbites. In order to gradually realign the teeth and jaws. The therapy may involve the use of braces or other orthodontic tools. The specific treatment strategy will determined by the degree of the underbite and the unique requirements of the child.
- Functional appliances: In some instances, children with underbites may benefit from functional equipment in addition to braces. These devices aid in modifying the jaws’ growth and positioning so that they guided into a more advantageous alignment. To maximise a child’s potential for growth, functional appliances frequently employed on growing kids.
- Early intervention: Treating underbites in children requires prompt action. Early intervention may help to direct the growth and development of the jaws, reducing the need for more intrusive treatments like surgery in the future.
