Summer, this passionate season, calls for vibrant colors in your attire. However, when you flash that sweet smile, yellowed teeth—caused by smoking, tea stains, or plaque buildup—can significantly detract from your overall image.
Many opt for professional teeth cleaning, but frequent sessions can weaken teeth and offer only short-term results. With rapid advancements in medical aesthetics, numerous safe and efficient teeth whitening methods now exist, effortlessly delivering a brighter smile.
As demand for teeth whitening grows, aesthetic whitening methods continue to evolve. What techniques are available this summer?
Cold light whitening,皓齿 whitening, and porcelain veneers are currently the most popular scientific whitening options. Who are these methods best suited for, and what are their respective advantages and side effects?Let's explore them together!
Cold Light Teeth Whitening: Uneven Shading & Surface Discoloration
Cold light teeth whitening utilizes high-intensity blue light with wavelengths between 480-520 nanometers. This light is transmitted via fiber optics through two specially coated optical lenses with over 30 layers, undergoing specialized optical processing to filter out all harmful ultraviolet and infrared rays.
Suitable for: Most cases of unexplained tooth discoloration; extrinsic staining (tobacco, coffee, cola, etc.); intrinsic staining (tetracycline teeth, etc.); fluorosis; congenital uneven coloration.
Treatment Cost: ¥1,500–3,500
Procedure:Teeth cleaning — Pre-treatment photography — Lip protection — Gum protection — Teeth whitening treatment — Post-treatment comparison. During the procedure, whitening agent is applied every 15 minutes for a total of 3 applications, with the entire process lasting 2 hours.
Side Effects: Teeth may feel sensitive for 3–5 days post-treatment, gradually subsiding after 5–7 days.
Precautions: Avoid hot/cold beverages for 24 hours post-treatment. To prevent increased pigment absorption after cold light whitening, refrain from consuming staining foods (e.g., spicy hotpot, betel nut chewing) for one week. Regular dental check-ups and cleanings maintain whitening results.
Haochi Whitening:Age-related yellowing, extrinsic staining
Utilizes low-temperature nano-light technology, completely eliminating discomfort caused by nerve stimulation during the procedure. The hydrophilic whitening agent and gum-free application process cause no damage to teeth or enamel.

Most importantly, minimize dark-colored foods in daily diet and maintain oral hygiene by brushing and rinsing morning, noon, and night to keep mouth clean.Since bacteria cannot survive on the porcelain surface, they not only whiten teeth but also prevent cavities.
Suitable Candidates: Ideal for moderate to severe cases of tetracycline staining, fluorosis, enamel hypoplasia, or teeth with cracks, fractures, pits, and significant defects. Offers highly noticeable whitening results.
Procedure Cost: ¥4,000–¥30,000
Treatment Process: Determine number of teeth requiring crowns → Administer anesthesia, prepare teeth → Take impressions, fit temporary crowns → Select crown shade → Crowns fitted after 5–7 days.
Side Effects: Metal allergies may cause sensitivity or swelling around teeth post-procedure.
Precautions: Porcelain crowns are generally suitable for ages 20-60. Preparation requires thinning existing teeth, posing risks for adolescents with immature permanent teeth and large pulp chambers.For older individuals, factors like gum recession, tooth mobility, overall health, and psychological considerations must be evaluated case-by-case. Additionally, patients with severe grinding or clenching habits may not be suitable candidates.
