Types of braces

The short version

Type	Visibility	Best suited to	Relative cost
Metal	Obvious	Any case; the default for teenagers and complex mechanics	Lowest
Ceramic	Subtle at conversational distance	Adults and older teens who want discretion without aligner compliance	Moderate premium
Self-ligating	Similar to metal or ceramic	Cases where fewer ligature changes and easier hygiene help	Small premium
Lingual	Invisible from the front	Adults who cannot show appliances at all	Highest

What is the same in all of them

Every fixed system works the same way. A bracket is bonded to each tooth and acts as a handle. An archwire threaded through those handles wants to return to its own shape, and in doing so it delivers light continuous force to the teeth. Bone remodels around the moving root, which is why orthodontics takes months rather than weeks and why heavier force does not produce faster movement.

Because the biology is identical, no bracket system moves teeth meaningfully faster than another. Claims of dramatically shorter treatment based on hardware alone do not hold up. What genuinely changes duration is the difficulty of the case, whether teeth are extracted, whether elastics are worn as instructed, and whether appointments are kept.

What actually differs

• How the wire is held. Conventional brackets use a small elastic ligature. Self-ligating brackets use a sliding or hinged door built into the bracket.
• What the bracket is made of. Stainless steel, ceramic, or occasionally a composite. Material affects appearance, friction and fracture resistance.
• Which surface it is bonded to. Nearly all braces sit on the cheek side. Lingual braces sit on the tongue side, which changes everything about wearing them.
• Bracket prescription. The angles built into each bracket differ between systems. This is invisible to patients and matters a great deal to the finish.
