Whether you’re 16 or 60, you can go for teeth straightening at any age. Although the ideal age is between 10-14 years while the mouth is still growing. The only limitation on age is that young children must have all their permanent teeth before starting orthodontic treatment.
Teeth alignment methods are effective for people of all ages if the correct orthodontic treatment is done. The only prerequisite is that your gums shouldn’t be weak since braces put some extra pressure on the teeth as well gums.
