Welcome to Sierra Lakes Dental Group and Orthodontics

Sierra Lakes Dental Group and Orthodontics is here to serve the Fontana and nearby communities with comprehensive oral health care services. From general to specialty dentistry, we offer an extensive list of services, including emergency dentistry. If you have an urgent dental need, we are here to help 24/7. Our teledentistry option makes it much easier for patients to get the care they need without even having to come in - connect easily with a dentist from your smartphone or computer. We accept many insurance plans. As we are always focused on helping you get the care you need, we have financing options that can be used with or without insurance. Research shows a strong link between oral and overall health?a concept we refer to as The Mouth-Body Connection. Heart disease, diabetes, and stroke are just a few of the conditions that your oral health can impact. So, if you want to live a healthier life, we recommend starting with your smile. Let us know how we can help!
