A few months ago,when I was reading a story to my 4-year-old granddaughter,she looked away and said that my breath was terrible. I didn't think much of it until it happened again the next week,and it wasn't long after I had brushed my teeth.
I've always kept up with oral hygiene(口腔卫生) ，so bad breath wasn't something that plagued me. I didn't notice it myself,but I asked my dentist about it soon after. According to him,bad breath is very common among old people. One of the major problems is that less saliva (唾液) is produced as we get older,which helps clean our mouth.
In the past,V ve used plenty of products that I thought would help with bad breath,but I didn't understand the real problem. Most ordinary mouthwashes that promise to kill bacteria(细菌) and give you fresh breath contain alcohol(酒精) They help fight bacteria,but it's only about an hour before your breath starts to stink(发臭) again. Even worse,the alcohol dries out your mouth,actually causing bad breath.
My dentist suggested an alcohol-free mouthwash. I did some research,and then tried a few products. SmartMouth Advanced Clinical Formula offered all of the advantages I was looking for,including a promise of 12 hours of fresh breath every time I used the product. It is alcohol-free,so it doesn ’t dry my mouth,but it still kills bacteria.
I knew SmartMouth was unusual because it was the only mouthwash on the shelf that came in a box,with two bottles inside. You combine the two in one cup right before using: that's what makes it so different from other mouthwashes. It does provide long-lasting fresh breath. This step “activates” the mouthwash,and the results speak for themselves. My granddaughter lovingly tells me that I'm no longer stinky.
