If stained or discolored teeth are making you feel self-conscious, you’re not alone. Everyday habits like drinking coffee, tea, or wine — along with aging and lifestyle factors — can gradually dull your smile. Fortunately, modern cosmetic dentistry offers safe and effective ways to restore a naturally bright appearance.
At Marina Aesthetic Dentistry, we offer both in-office professional teeth whitening and custom take-home whitening trays to help you achieve a radiant smile. Our whitening treatments are non-invasive, comfortable, and designed to deliver visible results quickly — often after just one visit or a few sessions of consistent at-home use.
With our personalized whitening solutions, you can safely remove surface stains, lift discoloration, and enjoy a noticeably brighter, more confident smile — without increased tooth sensitivity. Learn more
Most people experience some level of tooth discoloration over time, and it can result from a variety of internal and external factors. We help patients understand what’s causing their stains — and create customized whitening treatments to restore a bright, healthy smile.
Common causes of stained or discolored teeth include:
Poor dental care – Skipping daily brushing, flossing, or professional cleanings allows plaque and food buildup that can darken your teeth.
Foods and drinks – Coffee, tea, red wine, berries, and richly pigmented sauces are common culprits of surface stains.
Smoking and tobacco use – Nicotine and tar can lead to yellow or brown discoloration that’s difficult to remove without professional care.
Aging – Over time, enamel naturally wears down, revealing more of the yellow-toned dentin beneath.
Medical conditions – Certain illnesses like diabetes or metabolic disorders can affect the color and strength of your enamel.
Medications – Antibiotics, antihistamines, and some prescription drugs can contribute to deeper, intrinsic stains.
Whether your tooth discoloration is extrinsic (external) or intrinsic (internal), our San Francisco dentist can design a personalized whitening plan to safely remove stains and help you regain your bright, confident smile.
Our professional in-office teeth whitening treatments can dramatically brighten your smile in just one visit. The process is fast, comfortable, and non-invasive — even for patients with sensitive teeth. In about two hours, we’ll customize your treatment to achieve the perfect level of whiteness for your smile.
For patients who prefer whitening at their own pace, we offer custom take-home teeth whitening trays designed for comfort and consistent results. These trays can also be used to maintain your bright smile between professional treatments.
If tooth discoloration is accompanied by other cosmetic concerns, porcelain veneers may be the ideal solution. Veneers are ultra-thin, custom-made porcelain facings that cover the front surface of your teeth to conceal stains, chips, cracks, or gaps. They look completely natural and can give you a brighter, straighter, and more confident smile.

Dr. Patel and her amazing staff were incredible. Their kindness and compassion towards me was something I had never experienced in the US. I cannot thank them enough – and I could not recommend them higher.
She and her staff are always courteous and easy to work with. I’ve referred her to other San Francisco friends and their families and they’ve always thanked me for it. If you are looking for a dentist for cosmetic or general dentistry needs, Dr. Patel is a great choice.
I was referred to Dr. Patel by a coworker. I love everything about this office. I was able to communicate by email to make my appointment and they accommodated me in a very timely manner.
