Unfortunately, as we age, our teeth naturally become darker or yellower. Additionally, other factors such as smoking and the foods and drinks we consume will also impact the colour of our teeth. Some of the biggest culprits include red wine, coffee, tea, cola, curries, and anything with a high level of food colouring. Some surface staining can be removed with a professional clean and polish, but if a whiter result is desired, then other treatments, including teeth whitening or cosmetic veneers, may be other options worth considering.
