There are several types of toothpaste in the market these days, ones with fluoride to strengthen enamel, others with potassium nitrate that sooth the nerves inside your teeth, preventing them from sending pain signals from triggers, like a burst of cold air or hot coffee, others with antimicrobial agents that may contain stannous fluoride, an antibacterial agent that also provides anti-cavity and sensitivity benefits, ones that help remove and/or prevent stains from forming on the teeth with chemical or abrasive ingredients (whitening toothpaste). So, the one you really need depends on your particular needs.
