Led by Dr. Shawn Yazdanmehr, our Mission Valley dental practice combines the warmth and personal attention of a traditional neighborhood dental office with the precision and capabilities of advanced technology. We believe visiting our dental office should feel less like a chore and more like a positive part of your routine—a place where you can relax, ask questions freely, and receive honest guidance about your oral health.

We understand that choosing our practice means placing trust in someone who will be your partner in lifelong oral health, which is why we’ve built our practice on three core values: humanism, confidence, and transparency.

Damaged or missing teeth affect both your confidence and oral health. We understand how frustrating it feels to hide your smile or struggle with everyday activities like chewing. At Salt and Smile Dental Co, we provide dental crowns and bridges as proven solutions that bring back function and beauty to your teeth. Our approach combines traditional care with modern techniques, creating restorations that blend seamlessly with your natural smile.
A crown acts like a protective cap over a damaged tooth, while a bridge fills the space left by missing teeth. Both treatments use durable materials designed to last for years. Our dentist in San Diego works closely with you to understand your specific needs and create a personalized treatment plan. We take time to explain every step, answer your questions, and make sure you feel comfortable throughout our process.
Ignoring a cracked or weakened tooth creates bigger problems down the road. Small issues grow into painful emergencies that require more extensive treatment. Crowns protect vulnerable teeth from further damage and prevent the need for extraction. Our dentist carefully shapes and places the dental crown to restore your ability to chew properly and eliminate sensitivity that makes eating uncomfortable.
Here’s what crowns can fix:
Gaps in your smile create more challenges than you might realize. Your remaining teeth start shifting into empty spaces, throwing off your bite alignment. Chewing becomes difficult, forcing you to avoid certain foods. Bone loss occurs in the jaw where teeth are missing, changing your facial structure over time.
Our dentist performs the professional placement of bridges to prevent these complications and restore normal function:
We offer bridge solutions that restore your complete smile and bring back normal function. Our dentist guides you toward the best choice based on your oral health and personal goals. We believe in transparent communication and detailed explanations, so you always understand your options before making decisions about your treatment.
Losing a tooth affects more than just your smile. After our dentist removes a tooth, the empty socket begins a natural healing process that often leads to deterioration. Socket preservation is a procedure that protects the extraction site and maintains the structure of your jawbone. This technique helps create a stable foundation for future restorative work.
At Salt and Smile Dental Co, we understand how important it is to preserve your natural jaw structure after an extraction. Our approach focuses on preventing the complications that come with untreated extraction sites. We work with you to determine if socket preservation fits your oral health needs and long-term goals.
Certain situations make this procedure especially valuable for patients. People planning to get dental implants done by our skilled dentist in San Diego later benefit from having healthy jaw structure already in place. Teeth in visible areas of your smile need special attention because deterioration affects your appearance. Patients with existing density issues gain extra protection against further problems in the jaw.
Good candidates for our procedure include:
Planning ahead saves you time and discomfort down the road. Socket preservation gives you more treatment options in the future, even if you’re not ready to replace the tooth immediately. Our dentist can address the gap months or even years later without extensive reconstruction.
Our approach offers several advantages:
Most people heal without major complications after our procedure. Our dentist provides detailed aftercare instructions to help you through the process. Your oral health matters to us, and we stay available to answer questions and address concerns as you recover.
Missing teeth create challenges that go beyond appearance. Gaps in your smile make chewing difficult, affect your speech, and cause neighboring teeth to shift out of position. Dental implants provide a permanent alternative that mimics the structure of natural teeth. Unlike removable dentures or bridges that rest on top of your gums, implants anchor directly into your jawbone through a titanium post that acts as an artificial root.
The implant process involves our dentist surgically placing a fixture into a patient’s jaw, which naturally fuses with the surrounding bone tissue over several months. This biological bonding process, called osseointegration, creates a stable foundation that supports a custom porcelain crown. The result looks, feels, and functions like a real tooth. You can eat your favorite foods without worry, speak clearly, and smile with complete confidence.
Your jawbone requires constant stimulation to maintain its density and strength. Natural tooth roots provide this stimulation every time you bite or chew. After tooth loss, the bone in that area receives no pressure signals and begins to deteriorate. This shrinkage changes your facial structure over time, creating a sunken appearance around your mouth and lips.
Professional placement of implants by our dentist in San Diego as a tooth replacement actively prevents this deterioration:
At Salt and Smile Dental Co, we use advanced imaging technology to assess your bone density and create a precise treatment plan. The titanium posts integrate with your existing bone structure, essentially becoming part of your body. This unique characteristic sets our implants apart from every other restoration method available.
Traditional dentures sit on top of your gums and rely on adhesives or suction for stability. Bridges require grinding down healthy adjacent teeth to serve as anchors. Both options need replacement every several years as they wear down or lose their fit. Our dentist reshapes teeth on either side of the gap to ensure a secure fit and longevity of your restoration.
Key advantages that set our implants apart include:
Our implants use a three-part system designed for longevity. The titanium fixture serves as your new root, the abutment connects the root to the visible portion, and the porcelain crown completes your smile. Each piece works together to create a restoration that’s virtually indistinguishable from the teeth you were born with. You’ll forget which teeth are implants because they feel completely natural in your mouth.
At Salt and Smile Dental Co, we’ve created a comprehensive patient experience that prioritizes both your comfort and your oral health. Here’s what sets our dental office apart.
