Intro: All dental procedures, including cosmetic procedures, carry risks and have limitations. The information below is general in nature and is not a substitute for a consultation. Before any cosmetic treatment your dentist will examine your teeth and gums, discuss your options (including no treatment), explain the risks that apply to you, and give you time to consider your decision.
Porcelain veneers — Involves removing a thin layer of enamel, which is irreversible; teeth will always need a veneer or other restoration afterwards. Risks and limitations include: tooth sensitivity (temporary or ongoing); veneers can chip, crack, debond or wear and may need repair or replacement (typical lifespan varies and depends on bite, grinding, diet and oral hygiene); colour cannot be changed after placement and may not match adjacent teeth over time; gum irritation or recession around margins; possible need for root canal treatment if the tooth nerve is affected; not suitable where there is active decay, gum disease, insufficient enamel, heavy grinding or certain bite problems; ongoing maintenance and regular reviews are required.
Composite veneers — Less enamel removal than porcelain, but still may be irreversible. Risks and limitations include: staining and discolouration over time; chipping and wear, more so than porcelain; shorter typical lifespan and more frequent maintenance or replacement; sensitivity; gum irritation; results depend on the operator’s technique and the underlying tooth; not suitable in all cases.
Teeth whitening — Risks and limitations include: tooth sensitivity, sometimes significant, during and after treatment; gum and soft-tissue irritation; uneven results, particularly where there are existing fillings, crowns or veneers (these do not whiten); results are temporary and fade with diet and habits; some discolouration (for example tetracycline staining or fluorosis) responds poorly; not recommended during pregnancy, for children, or where there is untreated decay or gum disease; a dental examination is required before whitening.
Invisalign / clear aligners — Risks and limitations include: discomfort or pain, particularly when changing aligners; speech changes; treatment relies on wearing aligners 20–22 hours a day and results depend on compliance; treatment time can be longer than estimated; refinements may be needed; tooth movement can cause root shortening, gum recession or, rarely, loss of tooth vitality; not all bite or alignment problems can be treated with aligners; teeth will move back without lifelong retainer wear; attachments and interproximal reduction may be required.
Dental implants / All-on-X (where advertised) — Surgical procedure with risks including infection, bleeding, nerve injury, sinus involvement, implant failure or loss, bone loss around the implant, and the need for further surgery; healing takes months; long-term success depends on bone quality, general health, smoking and oral hygiene; ongoing maintenance required.
General — Every procedure requires a consultation and clinical assessment first. Costs, alternatives, and what happens if treatment does not go as planned will be explained before you consent. You may seek a second opinion. If you have concerns after treatment contact the practice.
