Methodology Disclaimer
How Oral Health Advisory compares and rates the products in its product guides.
How We Rate Products
Oral Health Advisory compares oral care products using information, research and customer feedback from publicly available sources. Our guides highlight brands we believe offer good quality and value, and do not cover every brand or product on the market. Products are rated with a scoring system built on the criteria we consider most relevant to how well an oral care product performs, summarised below.
Product offering
We compare what each brand offers in a category, such as what comes in the box, price, delivery, guarantees and returns.
Features and formula
We compare the features and ingredients that matter for each category, such as the whitening agent and its strength, LED design or brush modes, and anything that sets a product apart.
Customer experience and brand rating
What customers say matters. We look at feedback on third-party review sites and on brands' own websites.
Standards and recognition
We check that products are sold within the rules for their market, such as limits on peroxide strength, and note awards or certifications a brand has received.
OHA Scores
Each product in a guide gets a score out of 10 for each of the four criteria above, and its OHA Score is the average of the four. Scores are our judgement of how products compare on those criteria. They are not laboratory or clinical test results.
Our guides are general information. They are not a substitute for advice from your dentist about your own teeth.
How We Keep Guides Current
Products, formulas and prices change. We review our guides and show the date of the latest update on each one.
