DENTAL REASONS FIRST

What we use it for

Botulinum toxin relaxes the specific muscle it is injected into. In dentistry, that means the muscles of chewing and smiling.

Teeth grinding & jaw clenching

  • Relaxes the masseter muscles at the angle of the jaw
  • Can reduce the force of grinding and clenching, and ease jaw-muscle tension
  • Works alongside a night guard, which still protects your teeth from wear
  • Read: botulinum toxin for grinding & clenching

Square jaw from a large masseter

  • A masseter that has bulked up from years of clenching can make the lower face look square
  • As the relaxed muscle becomes less bulky, the jawline can look softer over the following weeks
  • Results vary and are temporary
  • Read: masseter treatment for a square jaw

Gummy smile

  • When the upper lip lifts high, more gum shows when you smile
  • A small dose relaxes the lip-lifting muscles so the lip sits lower
  • Suits gummy smiles caused by lip movement; other causes need different treatment
  • Read: gummy smile treatment options

Smile lines & facial lines

  • Crow's feet that crease when you smile
  • Horizontal forehead lines
  • Frown lines between the brows
  • Softens lines caused by muscle movement; results vary from person to person

YOUR VISIT

What happens at your appointment

Assessment first, treatment only if it suits you.

1

Assessment

Dr Celeste Ng asks about your symptoms and medical history, checks your teeth for signs of grinding, feels the jaw muscles, and looks at how your lips move when you smile.

2

Plan and consent

She explains whether botulinum toxin suits you, the dose she recommends, other options such as a night guard, and the possible side effects.

3

Injections

The area is cleaned and marked. A very fine needle is used, and each injection takes seconds.

4

Aftercare

For the rest of the day: don't rub or massage the area, avoid lying flat for a few hours, and skip strenuous exercise and saunas.

5

Review

The effect builds over several days, with the fuller effect usually at around two weeks. Dr Celeste Ng will advise when to review.

FAQ

Common questions about botulinum toxin injection

How much does botulinum toxin injection cost at Trust Dental?+

Prices before GST: masseter (jaw clenching, grinding or a square jaw), $650; gummy smile, $150; forehead lines or crow's feet, $350; frown lines between the brows, $200. Each price is per treatment area; Dr Celeste Ng decides the dose you need at your assessment. Treatment is not claimable under Medisave or CHAS.

Who performs the injections?+

Dr Celeste Ng, who is accredited by the Singapore Dental Council to perform botulinum toxin injection. In Singapore, a dentist must hold this accreditation before offering the treatment.

Can botulinum toxin help with teeth grinding and jaw clenching?+

Injections into the masseter (the large chewing muscle at the angle of the jaw) relax the muscle, which can reduce the force of clenching and grinding and ease jaw-muscle tension. It does not cure bruxism, and a night guard is still the main way to protect your teeth from wear. Dr Celeste Ng will assess whether it suits you.

How long does it last?+

The effect is temporary and wears off gradually as the muscle recovers, typically over several months. How long it lasts varies from person to person and between areas, so repeat treatments are needed to maintain the effect.

When will I see the effect?+

The effect builds up over several days, with the fuller effect usually seen at around two weeks. For the masseter, visible change in jaw shape takes longer, as the muscle gradually becomes less bulky over the following weeks.

Does it hurt?+

A very fine needle is used and each injection takes seconds. Most people describe a brief pinch. Mild tenderness or a small bruise at the injection site can occur and usually settles within days.

What are the possible side effects?+

Common, temporary effects include tenderness, swelling or bruising at the injection site and headache. Masseter treatment can make chewing tougher foods feel tiring for a while. Gummy smile treatment can occasionally make the smile temporarily uneven. Dr Celeste Ng will go through the risks at your assessment.

Who should not have botulinum toxin injection?+

It is not suitable if you are pregnant or breastfeeding, have a neuromuscular condition such as myasthenia gravis, have an infection at the injection site, or have had an allergic reaction to botulinum toxin before. Tell your dentist about all medicines you take.

Can I use Medisave or CHAS?+

No. Botulinum toxin injection is not claimable under Medisave or CHAS.

Is there any downtime?+

Most people return to normal activities straight away. For the rest of the day, avoid rubbing or massaging the treated area, lying flat for a few hours, strenuous exercise and saunas. Dr Celeste Ng will give you aftercare instructions.
