Why Do You Have Stained and Discolored Teeth?

Your smile plays a big role in how you feel and present yourself. At Smile Dentistry, we understand that stained or discolored teeth can affect your confidence and willingness to smile. Whether you're dealing with mild yellowing or more noticeable brown or gray discoloration, our experienced dental team is here to help you restore brightness to your smile.


Tooth discoloration occurs when the natural color of your teeth changes due to external or internal factors. These changes may appear on the surface (extrinsic stains) or within the tooth structure itself (intrinsic stains). During your consultation, our team will assess the cause and extent of your discoloration and help you determine the most effective treatment option.

Extrinsic Stains


  1. Surface Stains | These are caused by external factors that often affect the outer layer of the tooth (enamel). Common causes include the consumption of pigmented foods and drinks such as coffee, tea, red wine, berries, tomato-based sauces, and certain spices. Smoking or using tobacco products can also lead to extrinsic stains due to tar and nicotine.
  2. Poor Oral Hygiene | Inadequate flossing and brushing can result in the accumulation of plaque on your teeth. Plaque, when not removed regularly, can harden into tartar, which can cause surface discoloration that contributes to staining.


Intrinsic Stains


  1. Medication | Some medications, particularly certain antibiotics such as tetracycline, when taken during childhood, can cause intrinsic stains. These stains occur within the tooth's structure, making the stains more challenging to remove through regular cleaning.
  2. Trauma or Injury | Physical trauma to a tooth, such as a fall or impact, can cause intrinsic discoloration. This is because the tooth may react to the injury by laying down more dentin (the inner layer of the tooth beneath the enamel), which can darken the color of the tooth.
  3. Aging | Over time, the enamel of our teeth can wear away, revealing more of the yellowish dentin underneath. This natural process makes teeth appear more stained or discolored as we age.

Prevention and Treatment For Stained Teeth

Preventing stained teeth involves maintaining good oral hygiene practices, regular dental check-ups, and minimizing the consumption of staining foods and beverages. Professional dental cleanings can help remove surface stains, but if the stains on your teeth are deeper, treatments such as whitening, veneers (thin shells placed over the front of teeth), or crowns (caps that cover the entire tooth) may be recommended by our dentist to improve your tooth color.


Maintaining a bright, healthy smile involves a combination of proactive measures and professional guidance to prevent and address stained teeth effectively. Understanding the specific cause and type of staining is vital for determining the most suitable treatment plan. Consulting our dentist allows us to create a personalized assessment and recommendation based on your individual needs for any current stains you have on your teeth and to help prevent future staining.
