Can Adults Get Braces on the NHS? [2026 Eligibility Criteria]

The myth: "You can only get braces as a child on the NHS." The reality: adults can too—but almost none actually qualify. Here's how the system works, who meets the criteria, and what to do if you don't.

The Quick Answer

Can adults get braces on the NHS? Technically yes, but practically almost never. Fewer than 1% of NHS orthodontic cases are for adults over 18.

Why? The NHS only funds orthodontics for people with significant functional problems—not cosmetic concerns. For most adults wanting straighter teeth, NHS won't cover it.

What if you don't qualify? You're looking at private treatment, which costs £2,000-6,000+ for Invisalign or traditional braces.

How NHS Orthodontics Is Funded

The NHS budget for orthodontics is limited. Priority goes to children and teenagers because: 1. Teeth are more responsive to orthodontic movement in younger patients 2. Early intervention prevents more complex problems later 3. Children have decades to benefit from straight teeth 4. Public health strategy prioritizes youth dental health

Adults are deprioritized, which means unless you have a serious functional problem, you won't qualify.

IOTN Scoring: The Deciding Factor

Every person wanting NHS orthodontics is assessed using IOTN (Index of Orthodontic Treatment Need). This determines whether your bite problem is severe enough to warrant NHS funding.

IOTN has 5 grades:

The reality: Most people fall into Grade 1-2. You need Grade 4 or higher.

What Counts as a "Functional Problem"?

IOTN doesn't care if your teeth look crooked. It cares if crooked teeth cause actual problems:

Functional Problems That Might Qualify

• Difficulty chewing: Your bite is so bad you can't eat certain foods
• Speech problems: Your teeth affect how you pronounce certain sounds
• Jaw pain: Misalignment causes TMJ problems or jaw dysfunction
• Breathing issues: Severe malocclusion narrows your airway
• Oral hygiene challenges: Your crowded teeth are so difficult to clean that you have persistent decay/gum disease despite good habits

Problems That WON'T Qualify

• Cosmetic crowding: Your teeth are crooked but you eat and speak fine
• Low confidence: You're embarrassed about your smile
• Minor spacing: A small gap between your front teeth
• Slight overbite/underbite: If it doesn't affect function
• Wanting a "perfect" smile: Aesthetics alone don't qualify

Most people wanting braces have cosmetic concerns, not functional ones. That's why most don't qualify.

Getting an IOTN Score

Step 1: See your NHS dentist Ask them to assess whether you might be IOTN Grade 4 or 5. They're trained to recognize severe malocclusion.

Step 2: Request a formal assessment If your dentist thinks you might qualify, ask for an NHS orthodontics referral. Some dentists will do a preliminary IOTN score themselves; others refer you directly to a specialist orthodontist.

Step 3: NHS orthodontist assessment An NHS orthodontist will examine you and assign an official IOTN grade. This assessment is usually free.

Step 4: Wait and see If you're Grade 4+, you'll be added to a waiting list. Depending on your area, this could be 12-36 months.

What If You're Grade 1-3?

You don't qualify for NHS orthodontics. You have options:

Option 1: Private Fixed Braces

• Cost: £2,000-4,500
• Timeline: 18-24 months
• Type: Metal or ceramic (tooth-colored)
• Effectiveness: Excellent for all types of malocclusion

Option 2: Private Invisalign

• Cost: £2,500-6,000
• Timeline: 12-24 months
• Type: Clear aligners
• Effectiveness: Good for mild-to-moderate crowding; less effective for severe bite issues

Option 3: Do Nothing

• Cost: Free
• This is valid: Cosmetic concerns don't require treatment

Many people with Grade 1-2 malocclusion choose to leave their teeth as-is. It's a reasonable choice if function isn't affected.

IOTN Grade Examples

To help you understand where you might fall:

Grade 1-2 (Likely Not Eligible)

• Minor crowding of upper front teeth (1-3mm)
• Small gap (under 2mm) between front teeth
• Slight overbite (3-4mm) with no functional impact
• Slightly rotated canines

Grade 3 (Borderline)

• Moderate crowding (4-7mm)
• Obvious spacing (2-4mm) affecting appearance but not function
• Moderate overbite (4-7mm)
• One tooth positioned severely out of line but teeth otherwise well-aligned

Grade 4 (Likely Eligible)

• Severe crowding (over 7mm) affecting cleaning ability
• Large gaps between teeth
• Significant overbite/underbite affecting eating or speech
• Anterior open bite (upper and lower front teeth don't meet)
• Severe rotations affecting function

Grade 5 (Definitely Eligible; Priority)

• Very severe malocclusion affecting speech, eating, breathing
• Anterior open bite making normal eating impossible
• Combination of severe crowding and functional problems
• Jaw development issues affecting appearance and function

The Waiting List Reality

If you qualify (Grade 4+), here's what to expect:

Your Area's Waiting List Length

• London and major cities: 18-24 months typical
• Smaller cities: 12-18 months typical
• Rural areas: 24-36+ months possible

Why So Long?

• Limited NHS orthodontists (fewer than pediatricians, for example)
• Priority given to under-18s (children have priority)
• Complex cases take longer to treat
• Adult cases are deprioritized even among qualified adults

Managing the Wait

If you've been waiting 12+ months and haven't been called: - Contact your local ICB to check your status - Ask if treatment slots have opened up - Consider private treatment if the wait is unacceptable

NHS Braces vs. Private: What You Get

Adult Orthodontics Facts

Why Adults Can Get Braces At All

Teeth can move at any age as long as your gums and bone are healthy. Contrary to myth, adult teeth move as readily as children's teeth—it just takes slightly longer.

Why Adults Seek Braces

• Professional/romantic reasons: Career or dating motivations
• New confidence: Midlife or later-life decision to address previous concerns
• Previous gaps: Teeth shifted after previous braces, and they want them fixed
• Genuine functional problems: Now that it's affecting them, they want it fixed

Success Rate for Adults

Adult orthodontics has the same success rate as child orthodontics—over 95% of cases achieve the desired result. Age doesn't limit effectiveness if you're compliant.

When to Push for NHS Referral

Definitely ask for NHS referral if you have: - Difficulty chewing certain foods due to your bite - Speech problems caused by tooth position - Jaw pain or TMJ symptoms - Severe crowding that's causing decay/gum disease - Open bite where your front teeth don't meet

Don't bother asking if you have: - Minor cosmetic concerns - Slight crowding you're fine living with - Spacing that doesn't affect function - Just wanting a "perfect" smile

Your dentist will be honest about your chances. If they say "you don't qualify," that's usually accurate.

The Cost-Benefit Analysis for Adults

Private braces/Invisalign: £2,500-6,000 one-time cost

Is this worth it for you? Consider: - How long until retirement? (If 20+ years, the benefit is decades) - Does your bite affect eating or speech? (If yes, it's functional, not cosmetic) - Will it genuinely improve your quality of life? (If yes, it might be worth it) - Can you comfortably afford it? (Financial stress undermines the benefit)

Many adults find private orthodontics worthwhile because they've been wanting it for years and finally have the resources.

The Honest Assessment

NHS orthodontics for adults exists but is genuinely rare. The system prioritizes children and teenagers, which makes sense from a public health perspective.

If you don't qualify, private treatment at £2,500-6,000 is your option. It's expensive, but it's reliable and available immediately. Thousands of adults do it every year.

If you're borderline (Grade 3), ask your dentist explicitly about your chances. Don't assume you don't qualify without professional assessment.

Your IOTN grade matters more than you think. It's not subjective or negotiable—it's a standardized clinical assessment. Once you know your grade, you know your realistic options.
