When Is Orthodontic Treatment Needed?
Orthodontic problems are not only 'crooked teeth'; bite relationships often matter more.
Alignment problems
- Crowding, where teeth overlap due to lack of space
- Spacing between teeth
- Rotated teeth
- Impacted teeth that fail to erupt
- Midline shift
Bite problems
Overjet, underbite, open bite and deep bite affect function as much as appearance: biting becomes difficult, the palate can be traumatised, and uneven forces can strain the jaw joint.
Health benefits of orthodontic treatment
Brushes and floss cannot reach between crowded teeth, so plaque accumulates. Uneven bites also overload specific teeth, causing wear, cracks and recession.
Orthodontic Treatment Options
The appliance is chosen according to complexity, age and aesthetic expectations.
Metal brackets
The most common and predictable method, capable of every movement and the first choice in complex and extraction cases. Visibility is the only drawback.
Ceramic brackets
Tooth-coloured ceramic is far less noticeable and works on the same principle, though it is slightly more brittle and the ligatures can stain.
Lingual braces
Bonded to the tongue side and completely invisible from outside; suitable for adults with high aesthetic concerns, though initial tongue irritation and speech difficulty are common.
Clear aligners
Treatment with a series of transparent trays, removable for hygiene. Effective in mild to moderate cases; braces are more predictable for severe crowding and skeletal problems, and aligners depend on compliance.
The Orthodontic Process and Duration
Treatment proceeds to a plan with regular reviews, and duration varies considerably.
Diagnosis and planning
Panoramic and cephalometric radiographs, photographs and models allow full analysis. The cephalogram distinguishes dental from skeletal problems, which determines whether appliances, growth modification or orthognathic surgery is needed.
Preparation and start
Decay is treated and scaling performed first, since force over inflamed gums accelerates bone loss. Extraction may be needed for severe crowding.
Reviews and duration
Regular appointments adjust or replace the wire; missing them directly extends treatment. Simple corrections take months, comprehensive cases up to around two years.
The retention phase
Removing the braces does not end treatment: without retention, noticeable relapse occurs within months. A fixed retainer is bonded behind the front teeth; a removable one is usually worn at night. Retention is long-term.
Hygiene and Diet During Treatment
This is the most critical aspect of fixed appliance treatment: neglect leaves permanent marks on straightened teeth.
White spot lesions
Plaque around brackets causes mineral loss, leaving permanent white marks when the brackets come off — the earliest stage of decay and hard to reverse. Straight teeth with white marks is the saddest and most preventable outcome.
Correct cleaning technique
- Brush after every meal — twice a day is not enough with braces
- Use an orthodontic brush and interdental brushes
- Clean under the wire with superfloss
- A water flosser is effective around brackets
- Fluoride mouthwash strengthens the enamel
Foods to avoid
Hard nuts, ice, hard sweets and bone-in food break brackets, while sticky foods pull them off. Slice hard fruit and vegetables, and limit sugary and acidic drinks.
The Retention Phase After Treatment
The retention phase, lasting until the teeth settle into their new positions, is an inseparable second half of orthodontic treatment.
Why Retention Is Necessary
During tooth movement, the fibres and bone around the root remodel. When the brackets are removed the teeth are in their new positions, but the surrounding tissues need time to adapt fully. Throughout this transition the teeth tend to drift back toward their former positions.
A retainer holds the teeth against that tendency and buys time for the tissues to settle. Natural minor changes in the jaws also continue with age, so retention is treated as a long-term element in preserving the treatment outcome.
Fixed and Removable Retainers
A fixed retainer is a fine wire bonded to the tongue or palatal side of the teeth and is not visible from outside. Because it does not depend on the patient inserting it, continuity is high; on the other hand, interdental cleaning must be meticulous to prevent calculus building up around the wire.
Removable retainers may take the form of clear trays or designs made from wire and acrylic. Their effectiveness depends entirely on regular wear. Clinicians often plan both approaches together; the duration and daily hours are set individually according to the initial crowding and the type of treatment.
Points to Watch During Retention
- Adhering to the daily wear time set by the clinician
- Cleaning the retainer after each use and keeping it in its dry case
- Not wrapping it in a napkin and leaving it on a table, the most common cause of loss
- Not rinsing it in hot water, as trays and acrylic distort
- Booking an appointment promptly if a fixed wire feels broken or detached
- Using an interdental brush and suitable floss around a fixed wire
- Consulting the clinician rather than simply stopping wear if the retainer feels tight
How Orthodontic Treatment Differs in Adults
In adults, orthodontics is usually planned not on its own but alongside gum and prosthetic treatment.
How Planning Changes Once Growth Is Complete
In children and adolescents, growth is an advantage that can be used to guide the jaw relationship. Once growth is complete, treatment is built directly around tooth movement. Crowding that looks identical may therefore require different mechanics in an adult.
In adults the biological rate of tooth movement can be more measured, and the condition of the supporting tissues may limit the plan. On the other hand, adult cooperation is usually strong; adherence to the appointment schedule and wear instructions makes the duration predictable.
Joint Planning With Gum and Prosthetic Treatment
A history of gum disease is common in adults. Tooth movement is not planned while inflammation is active; periodontal treatment is completed first and the tissues restored to health. Plaque control is also monitored more closely throughout treatment.
In patients with missing teeth, orthodontics can create an appropriately sized space for an implant or bridge. Uprighting tipped molars helps prosthetic treatment be carried out on a sounder foundation. The plan is therefore built by setting orthodontic and prosthetic goals together.
What Is Assessed First in an Adult Patient
- Gum health and the level of bony support
- The condition of existing fillings, crowns and bridges
- Missing teeth and whether neighbouring teeth have tipped into the space
- Pain, noise or restricted movement in the jaw joint
- The presence of a clenching or grinding habit
- Worn tooth surfaces and areas of gum recession
- Daily routine and the practicalities of attending appointments
