Dog breath!

Dear Pet lovers
Oh dear, I don't want to mention this to Jasper, but he has bad breath
Poor dog. How can I let him know without upsetting him? Is there anything he could take to help? There has been no change to his diet, so not sure why this is happening. His teeth are fine...when he lets me look
