Treatment comparison

Metal braces, ceramic braces, or Invisalign

Metal and ceramic braces use fixed brackets and wires; clear aligners use shells that move teeth with gentle pressure.

[1][2][3]

The short answer

Metal braces use brackets and wires, ceramic braces use tooth-coloured brackets, and clear aligners use plastic shells.

Choose fixed braces for bracket-and-wire control

Fixed braces use brackets and wires to put pressure on teeth, with elastics sometimes added to help move teeth and correct the bite.

[1][2][4]

Choose aligners for a discreet shell

Clear aligners are nearly invisible shells that snap over the teeth and gradually reposition them with gentle pressure.

[1][2][3]

What affects orthodontic cost?

Private brace cost varies with the complexity of the dental problem and the type of braces fitted. Adults usually pay privately in the NHS system.

Practical differences between orthodontic options
OptionPractical distinction
Ceramic bracesUse tooth-coloured or clear brackets or wires and tend to move teeth faster than clear aligners.[1][2][3]
Clear alignersNearly invisible plastic shells that snap over teeth and apply gentle pressure.[1][2][3]

What does each system require during treatment?

Fixed braces stay attached while they move teeth. Aligners must be worn as a series of shells, and a new-user adjustment period of about a week with mild early discomfort is common.

[1][2][4]

What problems can occur?

Hard and sticky foods can damage braces. A broken wire or bracket needs prompt orthodontic guidance, and wax can cover a sharp edge temporarily. Clear aligners commonly cause mild discomfort for the first few days, with an adjustment period of about a week. The discomfort is temporary and may be relieved by rinsing with warm salt water.

[1][2][4]

When might aligners not be suitable?

Clear aligners are not right for everyone; some cases are treated more predictably with braces or a combination of approaches.

[1][2][3]

What should decide between them?

The comparison should account for the movement and bite correction required, whether a fixed or removable system is practical, visibility, and the complexity of the problem. Brackets and wires apply pressure to move teeth, and elastics may add force for tooth movement and bite correction. Clear aligners snap over teeth and reposition them gradually with gentle pressure.

Frequently asked questions

Are clear aligners always less painful than fixed braces?

Mild discomfort is common during the first few days with clear aligners, and the evidence compares pain and quality-of-life effects between aligners and fixed appliances rather than declaring one universally pain-free.
