Bad taste and smell

I'm sorry to hear about the issues you're experiencing around your veneers, including the bad taste and smell. This could be related to the decay in your back tooth. It's important to treat it promptly to prevent any potential impact on your veneers and overall oral health. Please schedule an appointment so we can take a closer look and address the problem effectively.

Best regards,

In general, what you describe suggests that you may not have had a thorough comprehensive exam before getting your composite veneers. Bad taste and smell can come from a variety of untreated issues, including but not limited to cavities, moderate to severe gum disease, dental abscess, and more. When left untreated, cavities tend to grow deeper over time - this is why you may not have noticed a bad taste until now.
While many patients desire cosmetic care, it is crucial to rule out these conditions before any cosmetic work is done. Even with the best at-home hygiene care, existing dental conditions cannot be cured once they exist (regardless of what influencers on social media will have you think).
I highly recommend you get a full exam with complete set of xrays and consider any recommendations to treat the findings of that exam.

You make a valid point regarding the porosity of resin materials used in dental bonding. It's true that over time, composite resins can become contaminated as they tend to be more porous, which may trap microscopic food particles, potentially leading to bad odors. This is why ceramic restorations, such as porcelain veneers, are often more effective.

When you’re considering enhancing your smile, it's essential to be aware of the long-term effects and maintenance required for different types of dental treatments. Porcelain veneers, being made from a non-porous ceramic material, do not have the same issues with staining and odor retention as resin-based bonding. They offer a more durable and aesthetically pleasing solution that can resist stains and wear for many years, making them a superior choice for major cosmetic improvements.

If you are looking for a long-term solution with minimal maintenance and a consistent appearance, porcelain veneers would be a worthwhile investment. They provide a custom-fit, highly resistant option that maintains its color and integrity over time, addressing not just aesthetic concerns but also offering a practical, long-lasting solution.

Discussing these options with a cosmetic dentist will help you make an informed decision based on your specific needs and lifestyle. They can provide detailed insights into the benefits and limitations of each treatment, guiding you toward the best choice for achieving a vibrant and healthy smile.
