Tooth Gems

Tooth gem questions

What are tooth gems? +
Semi-permanent jewels bonded to your tooth enamel using dental-grade adhesive. Swarovski crystals, opalite charms, and 18K gold pieces. No drilling, no pain, lasting 1 month to over 2 years.
Are tooth gems safe? +
When applied by a qualified professional using dental-grade materials, tooth gems are completely safe. No drilling required — bonded directly to enamel using the same adhesive techniques used in general dentistry.
How long do tooth gems last? +
Swarovski crystals typically last 1 month to 2 years. 18K gold charms can last 6 months to over 2 years. Longevity depends on dental health, eating habits, and oral hygiene.
Does getting a tooth gem hurt? +
No. Completely painless. No drilling, no injections, no anaesthesia required. Most clients describe the process as comfortable.
Can tooth gems damage my teeth? +
When applied and removed correctly by a dental professional, tooth gems cause no damage to enamel. The bonding process is the same as placing orthodontic brackets.
How are tooth gems removed? +
Tooth gems should ONLY be removed by a dental professional. Do not attempt removal at home as improper technique can damage your enamel.
Which tooth is best for a gem? +
The upper canine is most popular for maximum visibility when smiling. Upper central and lateral incisors are also common. We discuss placement during consultation.
Can men get tooth gems? +
Absolutely. Tooth gems are for everyone. We see increasing numbers of male clients choosing subtle single crystals or gold charms.
Teeth Whitening

Whitening questions

What is professional teeth whitening? +
A cosmetic dental treatment performed by registered dental practitioners using dental-grade whitening formulas containing up to 44% hydrogen peroxide — over 7x stronger than cosmetic-grade products.
How long does a session take? +
60–90 minutes including pre-treatment assessment, whitening application (3–4 cycles of 15 minutes), and post-treatment review. Most clients see 2–8 shades whiter in a single session.
Is teeth whitening safe? +
Professional teeth whitening performed by a registered dental practitioner is safe. Products are TGA-approved and dental-grade. Some temporary sensitivity is normal and resolves within 24–48 hours.
How many shades whiter will I get? +
Most clients achieve 2–8 shades improvement in a single session. Results vary depending on staining type, natural tooth colour, and dental history.
How long do results last? +
6–12 months depending on diet and oral care. Regular coffee, tea, red wine, and tobacco accelerate staining. Using a straw and rinsing after staining foods helps significantly.
Will my teeth be sensitive? +
Some temporary sensitivity is normal and resolves within 24–48 hours. We use desensitising agents during treatment and provide a sensitivity management protocol.
