Orthodontics is one of the best-known dental specialties and, at the same time, one of the most misunderstood. Many people associate it solely with aesthetics, but its function goes far beyond simply straightening teeth .
In this article we explain what orthodontics is, what it is for, what types exist and how the treatment works , in a clear and understandable way.
What is orthodontics?
Orthodontics is the branch of dentistry that deals with correcting the position of the teeth and the relationship between the jaws . Its main objective is to achieve a functional bite and proper dental alignment, which directly impacts oral health.
Orthodontic treatment not only improves your smile, but also helps prevent problems such as tooth wear, chewing difficulties, or certain jaw joint disorders.
What is orthodontics for?
Orthodontics is used to correct different types of malocclusion , that is, a misalignment of the teeth or an incorrect relationship between the upper and lower jaw.
Among the most common problems it addresses are:
- Dental crowding
- Excessive spacing between teeth
- Crossbite
- Open bite
- Overbite
- Prognathism or retrognathism
In addition to improving the design of the smile, orthodontics facilitates better hygiene , reduces the risk of cavities and periodontal disease, and contributes to more efficient chewing.
How does orthodontic treatment work?
Orthodontics is based on the application of gentle, controlled forces to the teeth to gradually move them into their correct position. This movement occurs thanks to the bone’s ability to remodel over time.
The process is gradual and requires periodic checkups to adjust the system and ensure that the teeth move safely and effectively.
Types of orthodontics
There are different types of orthodontics, which are chosen based on the patient’s needs and the professional diagnosis.
Orthodontics with metal braces
It’s the most traditional option. It uses metal brackets bonded to the teeth and an archwire that guides their movement. It stands out for its effectiveness in all types of cases.
Aesthetic braces
They work the same as metal ones, but are made with more discreet materials, such as ceramic or sapphire, which makes them less visible.
Lingual orthodontics
The braces are placed on the inside of the teeth, so the treatment is virtually invisible from the outside.
Invisible orthodontics
It uses clear, removable aligners that are changed periodically. It’s a very popular option due to its comfort and appearance.

Phases of orthodontic treatment
An orthodontic treatment is usually divided into several stages:
- Initial study:
Case evaluation using radiographs, photographs, and dental models. - System placement:
Installation of brackets or delivery of aligners. - Adjustment phase:
Periodic check-ups to guide tooth movement. - Retention phase:
Use of retainers to maintain the results obtained.
The retention phase is essential to prevent the teeth from shifting again.
How long does orthodontic treatment last?
The average duration of orthodontic treatment is usually between 12 and 24 months , although it can vary depending on:
- The complexity of the case
- The type of orthodontics used
- The patient’s age
- Consistency in check-ups and care
Each case is unique, so the exact time should always be assessed by a professional.

Orthodontics can be performed at any age.
- In children , it helps guide the development of the jaws.
- In adolescents , this is the most common time, as the bone is still growing.
- In adults , it corrects functional and aesthetic problems, although the treatment may require a little more time.
