We Build Relationship, Not just Smiles



We Build Relationship, Not just Smiles

Everything we do at our practice is to the best of our ability. We pay attention to details, thorough and careful.
We put a lot of effort in ensuring that the precision we are working to is as fine as it can be. Every effort is made to ensure that our patients are delighted with all aspects of their treatment and our service.

Any dentist cannot sincerely and specifically predict how long his dentistry will last beyond the number of years he has been in practice. As we are dealing with human beings, biological tissue and ceramics we cannot guarantee the duration of a restoration or prosthesis in a patient's mouth.We can only offer predictions based on an epidemiological independent clinical studies.

Inevitably, a certain percentage of restorations will break for a variety of reasons, some biomechanical others through carelessness or accident. Despite the best will and treatment, very occasionally restorations do not last as long as they should do or require updating for other reasons.

Our commitment to excel in our profession is further evident by our unique
approach to stand behind our treatment to you.

As a result, we offer limited dental warranty for the investment you have made in your dental health.
Our goal is not only to treat your current dental problems but also to educate you in
preventing further dental problems.

We would like to be proactive in helping you maintain your oral health at its
best for the years to come.

It is our commitment to remain your partners for life in achieving your optimal dental health, of course, if you choose so.


The Warranty refer to the entire work done, i.e. all materials, labor work and treatment. It is only valid for procedures that were done in our clinic. Costs arising from work done in other dental offices are not covered under our warranty. The warranty of any of our treatment is only valid if our dentist completes the full work. If a problem arises during the 3 years warranty period, the patient has to contact the clinic as soon as the problem arises.

1 All warranties and conditions expressed or implied by statute, common law, equity, trade, custom or usage or otherwise howsoever are to the extent permitted by law expressly excluded from the Sales Contract. The Patient acknowledges that neither the Company nor any person purporting to act on its behalf has made any representation or given any promise or undertaking which is not expressly set out in the Sales Contract whether as to the fitness of the Services for any particular purpose or any other matter.

2 The Patient acknowledges that without relying upon the skill or judgement of the Zenaidy Castro P/L or any person purporting to act on its behalf it has determined that the Services conforming to the contract description will be fit for its purposes. Any description of the Services and/or Goods used in the Sales Contract is for identification only and shall not constitute a contract of sale by description. The provisions of this clause 4 shall not apply insofar as their application is prevented by the Trade Practices Act 1974 as amended or any other State and Territory laws.
3 Subject to the terms of the Supply Contract, the Company offers certain limited dental warranties in relation to the Services and/or Goods it provides to the Patient. The Patient acknowledges that the long-term success of any dental treatment provided by the Company corresponds directly to the Patient's home care, regular dental check-up and professional cleanings. As a pre-condition to the operation of any limited warranty provided by the Company, the Patient agrees that:

a) Following the completion of treatment, a Patient will attend a minimum of two (2) examinations and scale and clean in each year, and has followed the recommended preventative dental treatments and maintenance program as recommended by the Company. It remains the Patient's responsibility to contact the Company to make an appointment, and attend the six-monthly exam and prophylaxis failing which the limited warranty will be forfeited. It remains a fundamental condition for the operation of any limited warranty under the Sales Contract that the Patient maintains professional cleanings and check up/exams at the Company's office as often as is recommend by the Company (usually 2-4 times a year).

b) A bite splint is worn at night as recommended by the Company in cases where the dentist detects a history of grinding and/or clenching.

c) There is no outstanding balance on the Patient's account or monies owing to the Company unless otherwise agreed to by the parties in writing.

4 The Company is confident of the durability of the treatment it prescribes for its Patients.
a) Primary to a Patient's long term success is spending a few minutes a day on home care including but not limited to: brushing, flossing, using fluoride and prescribed products.
b) A secondary factor is regular professional examinations, cleanings, x-ray films and fluoride treatments ( at 2-6 month intervals depending on the Patient's condition). This warranty does not cover accidents that cause damage to the teeth or dental prosthesis. This limited warranty is only between the patient and the Company and does not include any agreements or contractual terms with insurance companies or any third parties. They will be billed in full. Only that amount of out-of-pocket expense paid by the patient will be credited toward the fee for replacement service.

5 Teeth whitening is not included or covered by the Company's limited warranty under this clause or under the Supply Contract due to its high unpredictability.

6 Restorative dental treatments as provided by the Company are permanent and recommended as the most appropriate method of dental treatment at the time of the Patient's consultation. If for any reasons including financial reasons the Patient is not able to have the recommended treatment as presented by the Company and opts for a treatment regime which is assessed by the Company in its absolute discretion as less than optimal including but not limited to a short-term fix, patchwork or any other temporary measures until definitive treatment is provided then any limited warranties provided by the Company under any Sales Contract will not take effect.

7 In cases where it is difficult for the Company to predict the likely future outcome or diagnosis at that time, that a Patient's tooth will either most likely (or on a 50/50 chance) require a root canal treatment, any future root canal treatment is not covered by the Company's limited warranty.

8 If a Patient's current dental treatment fails and requires replacement or repair and consequently different dental materials, techniques or treatment due to clinical failure (ie failure not covered by the Company's limited warranty) and is deemed to be necessary as advised by the Company acting in its sole discretion, then only the difference in treatment fee will be due and payable by the Patient.

9 Failure by the Patient to have continuing care visits including x-ray and exams as recommended by Company as above voids any and all limited warranties. It remains at all times the Patient's responsibility to contact the Company to make an appointment, and attend the six-monthly exam and prophylaxis.

Treatments Under Limited Warranty

a) The Company gives a limited warranty on these procedures for a maximum period of three (3) years. The Zenaidy Castro P/L agrees to replace or repair these procedures at no additional charge to the Patient during this 3-year period if they break, are lost or debonded as a result of normal use.
b) This warranty does not operate in the following circumstances:

i) The crown, veneer or bridge has been damaged by trauma, accidents and excessive force by severe grinding and clenching of the teeth that could also break normal healthy teeth;

ii) Neglect such as new decay, misuse, abuse, accidents or additional dental treatment done elsewhere.

c) Failure of the tooth underneath the crown or onset of root infection is not covered by the warranty.

d) Root fillings and non standard treatments are not covered by the operation of this clause.

e) The Company cannot predict, if and/or when gum or nerve treatments may be required on the covered tooth. If needed, they will require payment of additional fees by the Patient. If a veneered or onlayed tooth is damaged or decayed to the extent that a crown is necessary, the full fee originally paid for the veneer or onlay will be applied by the Company in payment towards the crown and the Patient will only be liable for payment of the difference.

The prosthetic treatment provided is warranted for replacement at no cost should a failure occur under the following conditions. Failure constitutes technical and construction faults only and does not include recurrent decay due to poor patient oral hygiene; overload failure due to patient non-compliance in wearing a prescribed splint for grinding habits (if applicable); failure due to accident or injury; failure due to wilful or habitual damage (eg. nail biting); failure due to a change in the patient's perception of the aesthetics of the final case after completion of treatment or failure due to loss or damage whether or not due to negligence on the patient's behalf. Other dental professionals may be involved in the provision of services in complex treatment plans. Failure of treatments performed by other practitioners is not warranted.. The limited warranty period is for 3 years from the date of initial placement of the prosthesis, and is only valid if the patient returns for annual review appointment or as prescribed on your individual cases. These appointments are to review and check the prosthesis only and may include its cleaning, however they are not a substitute for regular recall examination and tooth cleaning services. Whilst the warranted period extends to 3 years, this does not mean that your prosthesis will not last longer if well maintained. In extreme rehabilitative or reconstructive cases, the dentition may be so compromised that even complicated, high quality prostheses may have a guarded or poor long-term prognosis. In such cases a normal warranty cannot be provided. If a normal warranty cannot be applied, it will be indicated in your treatment plan letter.

Sealants are plastic coatings placed on the biting surfaces of the teeth to prevent decay in the pits and grooves of the teeth (a Patient must floss and use fluoride to prevent decay between the teeth). The Company will repair or replace traditional sealants for a period of 3 years after placement if decay is present on the biting surface, or the required filling is not covered.

If the composite is a treatment recommended by the Company, it will replace or repair it in the event of failure for a period up to three (3) years. If the tooth breaks and requires a crown or onlay, the Company will credit the cost of the filling towards the crown or onlay. Fillings are covered by a three (3) year limited warranty providing the Patient attends for routine check-ups and maintenance (this usually means a minimum of every six months or as otherwise prescribed by the Company in the case of an individual Patient's needs). The warranty allows replacement free of charge if the filling itself has failed including the situation with the material itself has broken. The warranty does not cover failure of the tooth or filling either due to stress or impact fracture or due to secondary dental decay or the onset of root infection.

Root canal treatment statistically has a high success rate, however, on occasion it may fail. If the Company has restored the tooth as prescribed, but the Patient loses that tooth within three (3) years due to failure of the root canal, the Company will apply any payment by the Patient as a credit towards a replacement tooth excluding implants as a replacement.

The Company provides a warranty on all dentures and partials for a maximum period of up to three (3) years if a tooth chips or breaks under normal use. This warranty does not cover accidents such as dropping of dentures or accidental breakage. Full upper and lower denture Patients must be seen once every 12 months. Patients with some of their own natural teeth must be seen at the prescribed recall appointment (a minimum appointment of once every 6 months), and follow the Company's recommendations concerning x-rays, fluoride, and periodontal treatment, or this warranty is null and void
Other conditions where 3 years Warranty will be invalidated for denture patients:

  • patient neglects oral hygiene

  • the patient undergoes treatment or laboratory work provided by another dentist without a preliminary consultation with our dentist

  • self-treatment or intervention such as adjusting denture by non-dental means, etc.

  • the gum tissue, teeth bone or jawbone undergo pathological reduction.

  • in case of accidental damage (e.g. falls down, fight, accident or other events caused by drugs, alcohol or other materials, etc.)

  • accidents, modifications that come up during emergency interventions and that affect the performed dental treatment

  • a general illness occurring that has negative effects on the dental condition (e.g. diabetes, epilepsy, and osteoporosis, condition after x-rays or chemotherapy, etc.).

  • diseases of masticatory apparatus caused by general, infectious diseases, tumours, poisonings, etc., or the treatment of these illnesses

  • denture is not used properly

  • denture is not cleaned with dental cleaning supplies and tools

  • problem reported lately or patient cannot provide the defective denture (please, contact immediately if something happens to the denture!).

  • patient does not notify the clinic prior to exercising their guarantee

  • when the treatment received has not been paid in full and all current accounts have not been honoured

  • Immediate Complete or Partial denture is not included on the warranty

The following events are not covered in general by the Company's three year limited warranty:

a) Failure or repairs resulting from a Force Majeure Event, neglect, abuse, failure of supportive tooth or tissue structures, wilful damage to the prosthetics, improper adjustments or improper dental hygiene.

b) Failure to follow periodic (minimum 6 months or 3-6-9-12 months) dental visit as prescribed by the Company for professional exam, X-rays and cleaning.

c) Failure to complete necessary dental treatments as prescribed by the Company. The Company is not liable or responsible for the treatment or dental work done by any other dentists and there remains no obligation on the Company to rectify other dentist's work.

The Company cannot give a 100% foreseeable prognosis if and/or when gum or nerve treatments may be required on a covered tooth. If needed by a Patient such additional Services will require payment by the Patient of additional fees. Unless otherwise advised all recommended dental treatment(s) by the Company will be performed by Dr. Zenaidy Castro (with the exception of specialist treatments specifically recommended elsewhere).
