Why an Orthodontist in West Covina?


Orthodontist vs. Dentist

Orthodontists are dental specialists who have undergone additional years of training focused solely on the alignment of teeth and jaws. This specialized expertise allows them to diagnose and treat complex orthodontic issues that general dentists may not be equipped to handle. When it comes to straightening your teeth, an orthodontist is the best choice for comprehensive, specialized care. They offer a wider range of treatment options and are trained to customize treatment plans to each patient's unique needs.


Unlock the Life-Changing Benefits of Orthodontic Treatment

Orthodontic treatment is about more than just straightening teeth; it's about enhancing your quality of life. A well-aligned smile boosts your self-confidence, making social interactions more enjoyable and even opening doors professionally. A great smile can be a game-changer in job interviews and workplace interactions. Physically, straight teeth are easier to clean, reducing the risk of oral health issues like gum disease and cavities. Moreover, a balanced bite can alleviate physical discomfort, such as jaw pain and headaches. The benefits extend beyond the physical to improve your mental well-being, as a great smile can be a significant mood booster.

The Psychological Boost: Confidence and Social Interactions

A well-aligned smile doesn't just look good; it makes you feel good too. The boost in self-confidence you'll experience will make social interactions more enjoyable and can even give you an edge in professional settings like job interviews.

Professional Advantages: The Power of a Great Smile

In the professional world, first impressions matter. A great smile can be a game-changer, making you more memorable and positively impacting your career opportunities.

Physical Benefits: Easier Cleaning and Oral Health

Straight teeth are not just aesthetically pleasing; they are also easier to clean. This reduces the risk of oral health issues such as gum disease and cavities, contributing to your overall well-being.

Comfort and Well-being: Alleviating Physical Discomfort

A balanced bite is crucial for comfort. Orthodontic treatment can alleviate physical discomfort associated with misaligned teeth, such as jaw pain and headaches.

Beyond the Physical: Mental Well-being

The benefits of a great smile extend beyond the physical to improve your mental well-being. The confidence and comfort that come with a well-aligned smile can significantly boost your mood and overall happiness.

Transformative Care with Dr. Donggeun Lee

“I first saw Dr. Donggen Lee back in 2019. What an incredible doctor! He's so patient, caring, and attentive. I had to undergo some pretty hefty orthodontic treatment that would've required surgery had it not been for Dr. Donggeun Lee. He's so talented! I honestly can't recommend him enough. Truly, a phenomenal orthodontist, and I am very grateful to have been his patient. 10/10.”
