Your best smile.Discreetly.

Invisalign can treat many common concerns, including crowding, gaps and a range of bite problems. Your clinician will examine your teeth, gums and bite before confirming the safest and most appropriate option for you.

Every smile is different. Simpler cases may take a matter of months, while more complex treatment can take longer. After your digital scan, we will explain your personalised plan and expected timeframe before you decide whether to proceed.

Appointments are usually spaced several weeks apart, with virtual monitoring available where clinically appropriate. This helps us keep your treatment on track while reducing unnecessary trips to the clinic.

You may notice pressure or mild tenderness for a short time after changing to a new aligner. This is usually manageable and is a sign that the aligners are gently moving your teeth.

Yes. You remove your aligners to eat and drink anything other than cool water, so there are no fixed-brace food restrictions. For predictable results, most patients need to wear their aligners for around 20–22 hours each day.

Retainers are essential to help hold your teeth in their new position. We will explain your long-term retention plan and the options available to protect your new smile.

Yes. We offer Invisalign Teen and, where appropriate, Invisalign First and clear-aligner-supported expansion for growing smiles. Suitability depends on dental development, cooperation and the type of correction required.

Yes. You can pay in full, spread staged payments over three months, or apply for 12-month finance at 0% interest. Finance is subject to status, affordability, lender approval and terms. We will confirm your exact fee and payment options before treatment starts.

DNTL Group Invisalign treatment starts at £1,495 for Express. Lite is £2,100, Moderate is £2,300 and Comprehensive is £2,500. Your clinician will confirm the appropriate plan following your assessment and digital scan, with a complete written fee before you decide whether to proceed.

Your clinician will listen to your goals, examine your teeth, gums and bite, and discuss whether clear aligners are appropriate. A digital scan can create a detailed 3D record and help demonstrate possible tooth movements. You will receive an explanation of suitable options, likely timings, fees and retention before deciding.

Invisalign can treat many dental overbites, underbites and crossbites, particularly when the problem is caused mainly by tooth position. More complex jaw-related bites may require additional techniques or a different orthodontic approach. A clinical examination and scan are needed to identify the cause and recommend the safest treatment.

Attachments are small tooth-coloured shapes bonded temporarily to selected teeth to help an aligner apply precise forces. They are more discreet than fixed-brace brackets but are not completely invisible. Your treatment simulation allows the clinician to plan which attachments are genuinely needed for predictable movement.

Neither option is universally better. Invisalign is removable, discreet and digitally planned, while fixed braces may be preferable for particular movements, complex cases or patients who would find aligner wear difficult. Your clinician should explain the benefits, limitations and alternatives that apply to your bite rather than promoting one system for everyone.
