My teeth turned yellow from coffee and cigarettes. The clinic is offering whitening for 10-15 thousand rubles, but I see cheap systems online for 500-1000 rubles. What's the difference and is it worth paying extra for the clinic?
The main difference is in the concentration of the active ingredient and process control: clinics use strong formulas applied by a professional with gum protection, while at-home systems contain much less whitening agent for safety. Cheap kits work slower, the results are less noticeable, but the risk of tooth sensitivity is lower - though you might not see results at all.
Your choice depends on how yellow your teeth are and how quickly you need results: professional whitening gives visible results in one session, while at-home treatment takes about two to three weeks. If your teeth already react to cold, the clinic is safer - the dentist will account for sensitivity. But if budget is tight and you're not in a rush, you can try the at-home option, just stick to established brands rather than completely unknown ones.
The main thing is don't start with cheap systems from the internet, especially if your teeth are already sensitive. The active ingredient concentration is definitely much lower in those, but that's not the only issue. With at-home whitening, it's easy to leave the product on too long, apply it incorrectly, and then you'll burn your gums or end up with uneven results. Plus, nobody will check your enamel condition beforehand - it might turn out there are already micro-cracks under the yellow buildup, and whitening will make them worse.
At a dental clinic, the dentist will first examine your teeth, treat any cavities if needed, protect your gums with a special material, and monitor the whole process. You usually see results right away and they last longer. Yeah, it costs more, but the risk of complications is minimal. If money's tight - ask the clinic for a system for at-home use with the right concentration and detailed instructions. It'll be pricier than internet offers, but safer.
One more thing: if you keep drinking a lot of coffee and smoking, any whitening is temporary. Results can fade in a few months. So think first whether it's worth spending money if the source of the problem is going to stay.
Don't buy cheap systems from the internet, especially unknown Chinese ones - they often don't even list what's in them, and you can end up with dangerous chemicals. Professional whitening is more expensive because the dentist will first check the health of your teeth and gums, and then monitor the process so the enamel doesn't get burned. Home systems from decent brands (the ones they sell in pharmacies) do work, but they're slower and the results are weaker - and if your teeth are already sensitive from coffee, you could end up with even more problems.
