Treatment Risks

Treatment Considerations and Potential Risks

Your overall health and wellbeing come first. Our approach prioritises prevention and minimally invasive dentistry, and we will always recommend the most conservative option that’s appropriate for your needs.

In some situations, cosmetic, surgical, or restorative treatments may be recommended to improve the appearance, strength, or function of your teeth. These procedures can deliver excellent outcomes, but like any healthcare treatment, they can involve risks and side effects.

This page provides a general overview of potential risks associated with common dental treatments. Deciding to proceed with any treatment is a significant decision and should be carefully considered. Your suitability and individual risks will be discussed in detail with a registered dental practitioner during your consultation.

Dental Veneers

Sometimes, veneer treatment may be combined with other procedures such as gum reshaping/recontouring to improve the final aesthetic outcome. These procedures have their own risks and considerations. Your practitioner will explain if this is recommended for you.

All dental procedures carry risks. Before proceeding, you may wish to seek a second opinion from an appropriately qualified health practitioner. Alternative treatment options may be available. We encourage you to ask questions and request clarification at any stage so you can make a fully informed decision.

Veneer treatment is commonly completed over 2 to 6 appointments, depending on complexity. Most patients can continue normal daily activities throughout treatment, though some people may prefer additional rest depending on comfort levels.
Recovery can differ between individuals. In many cases, tissues settle within around two weeks, however healing timelines vary.

Veneers require ongoing care and routine reviews. Your dentist will recommend a tailored maintenance plan, and maintenance costs may be separate from your initial treatment plan.

Tooth preparation

  • Permanent enamel removal: Veneers usually involve removing a thin layer of enamel which does not naturally regenerate.
  • Sensitivity: Temporary sensitivity to hot/cold or pressure is common for some patients. In some cases, sensitivity may persist and require additional management.

Strength, lifespan, and cosmetic outcome

  • Chipping, cracking, or debonding: Veneers are strong but can fracture or come loose over time, especially with heavy bite forces, teeth grinding/clenching, or trauma.
  • Aesthetic concerns: Shade matching is performed carefully, but there is a chance the final appearance may not align fully with expectations.

Gum health considerations

  • Gum irritation or inflammation: Veneers that are difficult to clean around, or changes in oral hygiene habits, can contribute to gum issues.
  • Future repair or replacement: Veneers are not lifetime restorations. They may need replacement due to wear, damage, gum changes, or changes in neighbouring teeth.

After treatment: what you may notice

  • Normal discomfort or lingering sensitivity: Mild discomfort is common initially. Rarely, symptoms can persist.
  • Bite changes and minor adjustment: Your bite may feel different at first. Some patients require minor bite adjustments to feel comfortable.

Uncommon reactions

  • Rarely, patients may react to anaesthetic or dental materials. Please tell your dentist about allergies, sensitivities, or medications before treatment.

Invisalign (Clear Aligners)

Invisalign (and other clear aligner systems) are orthodontic treatments designed to gradually move teeth into improved positions using a series of removable, custom-made aligners. Aligners are typically worn for most of the day and changed regularly according to your treatment plan.

While clear aligners can deliver excellent results for suitable cases, outcomes depend on individual biology, starting tooth position, treatment complexity, and how closely aligners are worn as prescribed. As with any dental treatment, there are risks and possible side effects.

All dental procedures carry risks. Before proceeding, you may wish to seek a second opinion from an appropriately qualified health practitioner. Alternative treatment options may be available. We encourage you to ask questions and seek clarification so you can make a fully informed decision.

The information below is general in nature. Your dentist will discuss your specific circumstances, suitability, and expected outcomes during your consultation.

In some cases, Invisalign treatment may involve additional procedures such as:

  • Tooth shaping (interproximal reduction/IPR) to create small amounts of space
  • Attachments (small tooth-coloured resin buttons) to help guide tooth movement
  • Elastics (rubber bands) to assist bite correction
  • Refinements (additional aligners) to fine-tune the final result

These components have their own considerations, which will be explained if recommended for your case.

Treatment length varies depending on complexity and compliance. Most patients can continue normal daily activities throughout treatment.

Ongoing reviews, oral hygiene, and retainer wear after treatment are essential. Your practitioner will recommend a personalised maintenance plan, and additional costs may apply (e.g., retainers, replacement aligners, refinements if required).

Comfort and tooth movement changes

  • Pressure or soreness: Mild to moderate discomfort is common when starting aligners or changing to a new set. This typically settles within a few days.
  • Temporary bite changes: Your bite may feel different during treatment as teeth move. This is usually expected, but may sometimes require adjustments to the plan.
  • Speech changes: Some patients experience a temporary lisp or altered speech while adapting to aligners.

Oral health considerations

  • Gum irritation: Aligners or attachments may cause irritation to gums, cheeks, or lips, especially early in treatment.
  • Increased risk of decay or gum inflammation: If aligners are worn without adequate brushing/flossing, plaque can build up and increase the risk of cavities, gum disease, and bad breath.
  • Existing dental issues: Untreated decay, gum disease, or poor oral hygiene can affect suitability and outcomes.

Results and predictability

  • Results may vary: Tooth movement is influenced by biological factors and may not follow the plan exactly in all cases.
  • Need for refinements: Additional aligners may be required to achieve the desired result, especially for complex movements.
  • Aesthetic or functional dissatisfaction: While planning aims for the best possible outcome, final results may not fully match expectations in every case.

Wear time and handling

  • Insufficient wear time: Aligners generally need to be worn as prescribed (often 20–22 hours per day). If not worn consistently, treatment can take longer, become less predictable, or not achieve the intended result.
  • Loss or damage to aligners: Lost, cracked, or warped aligners can delay progress and may incur additional costs.

Attachments, tooth shaping, and related risks

  • Attachment debonding: Attachments can occasionally come off and may need replacement.
  • Tooth sensitivity after IPR: If enamel is gently reduced to create space, temporary sensitivity may occur.
  • Enamel wear: Improper handling, poor hygiene, or grinding can contribute to unwanted wear in some cases.

After treatment: what you may notice

  • Relapse (teeth shifting back): Teeth naturally tend to move over time. Wearing retainers as instructed is crucial to help maintain your result.
  • Retainer maintenance/replacement: Retainers may wear out, distort, or break and may need replacement over time.

Uncommon complications

  • Root resorption: Rarely, orthodontic tooth movement can contribute to shortening of tooth roots. This is uncommon but can occur, particularly in higher-risk cases.
  • Jaw discomfort (TMJ symptoms): Some patients may experience jaw discomfort or muscle fatigue during treatment, especially if there are bite changes.

Dental Implants (including All-on Implants)

Dental implants can replace one tooth, multiple teeth, or a full arch. Traditional implants replace missing teeth in specific positions. All-on treatments use multiple implants (often 4–6) to support a full arch of teeth.

We use careful planning and modern imaging (including 3D planning where appropriate) to guide treatment and reduce risk. However, surgery always involves inherent risks.

Prior to surgery, you may need to adjust certain habits (such as smoking) or medical factors to reduce complications and support healing. Long-term changes to diet and oral care may also be recommended to protect your outcome. Your dentist will explain what applies to you.

Implant treatment may involve additional procedures such as bone grafting (to improve bone volume) or a sinus lift (to create space in the upper jaw so implants can be placed safely). These procedures have their own risks and will be discussed if relevant to your case.

All dental procedures carry risks. You may wish to seek a second opinion from an appropriately qualified practitioner. Alternative treatment options may be available. We encourage you to ask questions so you fully understand the treatment, alternatives, and expected outcomes.

Implant treatment is commonly completed over 3 to 6 visits, depending on complexity. Some patients may need to modify normal activities briefly after surgery. Depending on your procedure and response, additional rest may be recommended.
Healing varies between individuals. Many patients feel significantly better within days, and tissues often settle over approximately two weeks, though full bone integration takes longer and is assessed case-by-case.

Implants and implant-supported teeth require ongoing monitoring and professional maintenance. Regular reviews may be recommended (often every 4–6 months depending on risk factors). Maintenance costs may be separate from initial treatment fees.

Surgical Risks

Implant placement occurs near important anatomical structures.

Upper Jaw

  • The upper jaw may have softer bones and is close to the sinus.
  • Possible complications include reduced implant stability, bone fracture, or sinus involvement (including accidental entry or perforation).
  • These complications may require additional procedures and may increase costs.

Lower Jaw

  • In the lower jaw, implants may be placed near nerves that supply sensation to the lip, chin, and tongue.
  • Swelling or surgical proximity can cause altered sensation, numbness, tingling, or discomfort.
  • These effects are uncommon and are often temporary, but in rare cases may be prolonged or permanent.

After surgery: what may occur

  • Unpredictable stability: If implants do not achieve enough initial stability, immediate loading (placing a fixed temporary bridge/crown quickly) may not be possible. A removable temporary appliance may be required during healing.
  • Implant failure: Rarely, an implant may fail to integrate with the bone (for reasons that can be biological and unpredictable).
  • Removal and replacement: A failed implant may need removal and possible replacement. Additional procedures may be required if bone volume is insufficient.

Recovery: what to expect after surgery

  • Swelling and bruising: Swelling is common and may peak around day 3–4, then gradually reduce.
  • Bleeding: Some bleeding is normal, and may occur for 24–48 hours.
  • Pain and discomfort: Discomfort can last several days, and sometimes longer. Pain relief may be prescribed or recommended.
  • Activity restrictions: Avoid strenuous activity for 24–48 hours, and avoid intense exercise (e.g., gym/sport) for up to 10 days if advised.
  • Tiredness: Feeling tired for the first 12–24 hours can be normal.
  • Smoking: Smoking significantly increases the risk of poor healing and implant complications, including infection and treatment failure.
  • Diet: Soft, cool foods are often recommended in the early stage.
  • Support at home: If sedation or general anaesthetic is used, you may need someone to assist you. Anaesthetic-related risks will be discussed with you by your dentist and, if applicable, the anaesthetist.

Teeth Whitening

Teeth whitening is a cosmetic treatment used to lighten tooth colour and reduce staining from food/drinks, smoking, and natural ageing. Whitening may be performed in-clinic under professional supervision, and may be supported with take-home whitening for maintenance (where appropriate).

All dental procedures carry risks. Not everyone is suitable for whitening. A dental assessment is required before treatment to check for cavities, gum issues, enamel wear, and existing restorations that may affect results. You may also wish to seek a second opinion or discuss alternative options. Please ask questions at any stage.

This section outlines general risks and considerations. Your dentist will discuss your specific circumstances during consultation.

  • Oral health first: For best outcomes, a check-up and professional clean may be recommended prior to whitening.
  • Existing dental work: Crowns, veneers, fillings, and bonding do not whiten the same way natural teeth do. Colour differences may occur.
  • Diet and staining: It is commonly recommended to minimise strongly coloured foods and drinks for around 72 hours, such as tea/coffee, red wine, curry, soy sauce, tomato-based sauces, beetroot, and similar staining foods/drinks.
  • Results and longevity: Whitening is not permanent. Re-staining depends on diet, smoking, oral hygiene, and your natural tooth structure. Many people notice fading over 3–6 months, and top-ups may be recommended depending on your plan.
  • Sensitivity: Some patients experience sensitivity during or after whitening (often a short sharp response to cold/hot). This is usually temporary, but can occasionally last longer.
  • Gum irritation: Temporary gum irritation can occur if whitening gel contacts soft tissues.



In many cases, take-home whitening kits are used over a period of days or weeks, depending on your treatment plan and desired outcome. Your dentist will provide personalised instructions to help you achieve the best possible results safely.

Ongoing oral health care and reviews may be recommended, and any future maintenance or top-ups may involve additional costs.
