Talk to your dentist about the products you’re planning to use to whiten your teeth. They may be able to determine whether or they’ll be effective for your particular discoloration or safe for use. If you have any small cracks in your teeth, your dentist may advise against using whitening products. The chemicals could irritate the tooth pulp if it’s exposed. Whitening solutions can cause chemical burns on your gums which can make them appear white or cause them to be. This is usually harmless and clears up on its own, but you should still get it checked out to make sure there isn’t heavy damage. In the meantime, stop using any products that caused this. The tissue should return to normal after a few days. A possible side effect of whitening your teeth is that they could become more sensitive. Some sensitivity is normal, but if your teeth become extremely sensitive to heat or cold, talk to your dentist to make sure your teeth aren’t damaged. The dentist may advise you to stop using whitening products or suggest a different one. Follow their instructions. Some whitening products can cause pain and inflammation in your stomach if you swallow it. Mild discomfort can be a normal side effect, but if you experience severe pain or diarrhea or vomiting that lasts longer than 2 days, visit a doctor to make sure there isn’t a serious problem. Stop using the product if you experience severe pain, vomiting, or diarrhea.

Summary: Check with your dentist before you whiten your teeth. Get medical care if your gums turn white or bleed. Talk to your dentist if your teeth become more sensitive. See a doctor if you experience severe stomach pain.


Before you get to properly repairing your jeans, you'll first need to cut the excess threads, or frayed edges caused by the tear. Take some scissors and try to cut reasonably close; you want to get rid of any protrusions, but you also don't want to lose any material you can otherwise save. Provided you haven't lost much material, you can usually mend smaller rips without using any patches. First, turn your jeans inside out; that way, when you sew, the new seams won't be as visible. Take a sewing needle and thread, and stitch back and forth until the rip is mended. Try to make the stitches as close as possible. If it's available, try to use thread that's the same as the seam as the rest of the jeans. In many cases, this will be a white or black thread. If the rip is in a conspicuous place far away from natural seams, it's recommended you choose a colour that best fits your jeans' regular colour (usually blue or black). Once you get the rip sewn up, you can proceed to cut the extra bits off. Be sure to cut the sewing thread as close to the jean material as you can. If there are any frayed edges you didn't catch the first time around, give them a cut now. Now that you've made the repair, you'll want to seal the jeans with an iron press. This will smooth out any creases and give your pants a fresh feeling of newness.

Summary: Cut off the frayed edges. Sew up the tear. Cut all excess thread and remaining protruding material. Give your jeans a once-over with a clothes iron.


All modern Macs come equipped with their own built-in malware protection. If your system is not configured to receive regular updates, malware can slip through the cracks. Click “System Preferences” in the Apple menu, then click “App Store,” and make sure the following two options are checked:  Automatically check for updates Install system data files and security updates If you’ve installed MacKeeper and are receiving pop-up messages claiming you have a worm virus, do not follow their links or enter your credit card information. MacKeeper is known malware and should be removed from your system. Because there are no Mac “viruses,” it’s likely that a suspected worm virus is actually a different form of malware, like adware (excessive and tricky advertisements) or ransomware (software that holds your files hostage until your credit card information is provided). Regardless of its type, you’ll want to remove it from your Mac.  Malwarebytes Anti-Malware for Mac and Sophos Antivirus for Mac will both scan for and remove all adware at no cost. There are many paid options to scan and remove malware from Macs, but they are not typically recommended by experts. Start your anti-malware program and find the link that says “Update” (or something similar). Before running a scan, you’ll want the program to have up-to-date malware information. The actual name of the button will vary depending on your anti-malware program. The scan will take several moments to complete. If the program finds malware, follow any prompts to “quarantine” the rogue files. This will remove them from your system without sending them to the Trash. To keep your computer free of malware (including worms), Apple recommends taking certain precautions when using the Internet.  Never open e-mail attachments unless they were sent from a legitimate source. Limit downloads to the Mac App Store and identified developers. Mac checks all apps on its App Store for viruses and trusts other developers registered with Apple. To configure this feature on your Mac, select “System Preferences” from the Apple menu, click “Security & Privacy,” then “General.” There, select “Mac App Store and identified developers.”
Summary: Make sure your Mac is up-to-date. Uninstall MacKeeper. Download and install an anti-malware program. Update your anti-malware software to the latest definition files. Click the “Start Scan” or “Scan Now”. Quarantine your malware. Avoid malware in the future.
